Algebra II & Math III StandardPBAEOY S.ID.4X X Statistics Standards for Algebra II/Math III Normal Distribution

6
Statistics Standards for Algebra II/Math III S-ID.4 Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.

7
Statistics Standards for Algebra II/Math III Normal Distribution The Normal Distribution is: “Bell-shaped” and symmetric mean = median = mode Larger standard deviations produce a distribution with greater spread. μ = 10, σ = 1 μ = 10, σ = 2

Statistics Standards for Algebra II/Math III Normal Distribution Example: The ACT is normally distributed with a mean of 21 and a standard deviation of 5. 1) Using the Empirical Rule, estimate the probability that a randomly selected student who has taken the ACT has a score greater than 31. 2) What percent of students score less than or equal to 31. 3) What does this tell you about an ACT score greater than 31? =.0250

Statistics Standards for Algebra II/Math III Normal Distribution Animal Cracker Lab The label on a oz. Barnum’s Animal Cracker box says that there are 2 servings per box. A serving size is 8 crackers. How many crackers do we typically expect to find in a box? How do you think Nabisco determined this number? Will every box have exactly this many animal crackers?

11
The graph at right shows the distribution of the number of crackers in a sample of 28 Barnum’s Animal Crackers boxes. The label on the box indicated that we should expect 16 cookies in a box. Based on the graph and statistics at right, how likely is it that a box contains less than 16 cookies? Why does Nabisco tell the consumer there are 16 cookies in a box? Statistics Standards for Algebra II/Math III Normal Distribution Animal Cracker Lab Mean = cookies Standard Deviation = 0.91 cookies n = 28 boxes

Algebra II & Math III StandardPBAEOY S.IC.1X X Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes

14
Statistics Standards for Algebra II/Math III S-IC.1 Understand statistics as a process for making inferences about population parameters based on a random sample from that population.

15
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes A statistic is a numerical summary computed from a sample. A parameter is a numerical summary computed from a population. A statistic will vary depending on the sample from which it was calculated, but a population parameter is a constant value that does not change.

16
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Suppose we wish to know something about a population. For example we might want to know the average height of a 17 year old male, the proportion of Americans over 70 who send text messages, or the typical number of kittens in a litter. It is often not possible or practical to collect data from the entire population, so instead, we collect data from a sample of the population. If our sample is representative of the population, we can make inferences, or in other words, draw conclusions about the population.

17
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Activity: Random Rectangles What is the size (area) of a typical rectangle in our population of 100 rectangles? Random Rectangles is used with permission from Richard L. Scheaffer

18
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Judgment Sample First ask students to take a quick look at the population of rectangles and then select 5 rectangles that they think together best represent the rectangle population. This is a judgment sample. Students record the rectangle number and the area of the rectangle for each of the five rectangles in the table provided and calculate the mean of the sample. Each student records their mean on the class dot plot on the chalkboard. Repeat this process 4 more times.

19
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes How do we ensure that we select a sample that is representative of the population? We choose a method that eliminates the possibility that our own preferences, favoritism or biases impact who (or what) is selected. We want to give all individuals an equal chance to be chosen. We do not want the method of picking the sample to exclude certain individuals or favors others. One method that helps us to avoid biases is to select a simple random sample. If we want a sample to have n individuals, we use a method that will ensure that every possible sample from the population of size n has an equal chance of being selected.

20
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes More about simple random samples. Suppose we wanted a simple random sample of size 4 from a class of 20 students. The class has 10 juniors and 10 seniors. Which of the following sampling methods would result in a simple random sample?

21
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes A)Write the names of each of the 20 students on a separate slip of paper, place the slips in a hat, mix the slips, and without looking selects four slips of paper. B)Beginning with the first row, use a calculator to pick a random number from 1 to 5. Count back to the student sitting in the seat designated by the random number and select this student for the sample. Repeat for each row. C)First puts the names of the 10 juniors in one box and the names of the 10 seniors in another box. Randomly selects 2 juniors from the first box and 2 seniors from the second.

22
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Back to Random Rectangles Use a calculator or a random digits table to select a simple random sample of size 5 from the rectangles.

23
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Random Digits Table There are 100 rectangles. First select a row to use in the table. Select two digits at a time, letting 01 represent 1, 02 represents 2, and so on with 00 representing 100. Skip repeats. Our Sample: 36, 79, 22, 62, 33

24

25
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Sampling Distribution 100 Samples of Size 5 mean = Sample Distribution 500 Samples of Size 5 mean = As the number of samples increases, the mean of the sampling distribution gets closer and closer to the mean of the population.

26
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Sampling Distribution 100 Samples of Size 10 mean = 7.67 square units Sample Distribution 500 Samples of Size 10 mean = square units As the sample size increases, the spread of the sampling distribution decreases. (The standard deviation gets smaller.)

27
Statistics Standards for Algebra II/Math III Understand and Evaluate Random Processes Big Ideas: When multiple samples are taken from the population, the values of the sample statistics vary from sample to sample. This is known as sampling variability. If the population distribution is not too unreasonably skewed, as more and more samples are taken from the population, the mean (center) of the sampling distribution approaches the population parameter. As the sample size increases, the spread of the sampling distribution decreases. The shape of the sampling distribution is approximately normal.

Algebra II & Math III StandardPBAEOY S.IC. 3 X X S.IC. 6 X X Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions

30
Three types of statistical studies are surveys, observational studies, and experiments. In a survey the researcher gathers information by asking the subjects questions. In an observational study, the researcher observes and records characteristics about the subjects. In an experiment, the research randomly assigns subjects to treatment groups and notes their response. For each of these three types of studies, if we want to make inferences (draw conclusions) that we can generalize from the sample to the population, the subjects must be selected randomly. If the sample of subjects is not randomly selected, we can only make conclusions about the sample

31
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions More on Observational Studies There are times when it is unethical or impractical to assign subjects to a treatment group. For example, if we wanted to measure the long- term effects of smoking, it would not be good to ask subjects to take up smoking. If we want to decide which math text book is best at improving student performance, it might be impractical to ask a group of teachers to teach one group of students using textbook A and another group of students using textbook B. In situations like these, rather than randomly assigning subjects to treatments (smoking, textbook A), we instead make observations of groups that subjects are already a part of. For example, we randomly select a group of smokers and randomly select a group of non-smokers and record our observations for both groups. Since the subjects are not assigned randomly to a treatment group, we may not conclude a cause-and- effect relationship from an observational study.*

32
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions More on Experiments An experiment allows us to study the effect of a treatment, such as a drug or some type of experience, on the subjects. For example to investigate if a new cholesterol medicine is more effective than a current brand, subjects could be randomly assigned to the treatment new medicine or old. In an experiment other factors that might also have an effect on the response are identified. Starting cholesterol level, exercise, diet, and weight might all have an effect on the subject’s final cholesterol level. The researcher may try to control some of these factors so that they are the same for both treatment groups. For example, all participants may be given the same diet. Randomization (randomly assigning subjects to treatments) helps to ensure that factors, such as being overweight or not exercising, are likely to be present in both treatment groups. A randomized, controlled experiment allows us to conclude that the treatment caused an effect (response). To be able to make inferences from the sample to the population, an adequate number of observations must be collected. This is called replication.

33
How were subjects selected? Random SamplingNo Random Sampling How were subjects assigned to treatment groups? Random Assignment May infer cause and effect AND May generalize findings from sample to the population May infer cause and effect, but Cannot generalize findings from sample to the population. (We can conclude that the treatment caused a response for this sample only.) No Random Assignment May generalize findings from sample to population, but Cannot infer cause and effect. Cannot generalize findings from sample to population AND Cannot infer cause and effect What conclusions may we draw from statistical studies? (adapted from Ramsey and Schafer’s The Statistical Sleuth)

Statistics Standards for Algebra II/Math III S-IC.5 Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.

39
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Activity: Sleep Deprivation Does the effect of sleep deprivation linger or can we “make up” for lost sleep? To test this, 21 volunteer subjects ages 18 to 25 were randomly assigned to one of two treatment groups. Both groups first received training on a visual discrimination task. One group was deprived of sleep for the first night following this training, but were allowed unlimited sleep on the next two nights. The second group was allowed unlimited sleep on all three nights. Both groups were retested on the third day. Used with permission from Beth Chance and Allan Rossman.

40
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Based on the graph and statistics below, do you think there is evidence that sleep deprivation on the first night might have had an effect on a subject’s improvement on the visual discrimination task? Explain. What is the difference between the means for the two groups?15.92

41
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Primary Question of Inference: If the treatment had no effect, is it possible that we would see this great a difference simply by chance (random assignment)?

42
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Let’s investigate. Here is the data for the 21 subjects: (A negative value indicates a decrease in performance.) Sleep Deprivation Group Unrestricted Sleep Group

43
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Simulation Write each of the improvement scores on a separate card. Shuffle the cards and deal them into two groups. The first group will be sleep deprivation. The second is unrestricted sleep. Find the mean of each group, then find the difference in the two means. Plot this value on a class dot plot and record the value on the class table. Repeat the process 4 more times.

44
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Simulation Continued Now let’s let technology take over and create the sampling distribution as more and more samples are selected. A Sleep Deprivation simulation, can be found in the Rossman/Chance Applet Collection. Look under Statistical Inference Randomization Test for quantitative response (two groups) Used with permission from Beth Chance and Allan Rossman.

45
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Computer Simulation of 1000 Trials Used with permission from Beth Chance and Allan Rossman. How likely is it to get a difference in the mean improvement score that is or higher by chance (random assignment)? 10 out of 1000 samples (1.0%) were or higher. Not very likely!

46
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Conclusion: Can we conclude cause and effect? Can we generalize our findings for the sample to a population? (Who is the population of interest in this study?) From the simulation we can see that the difference between the means of the two treatment groups (sleep deprived and unrestricted sleep) is very unlikely to happen simply by chance (random assignment). We conclude that sleep deprivation, even when followed by two nights of unrestricted sleep, did have an effect on subjects’ improvement on the visual discrimination task.

Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Activity: Distracted Driver Are drivers more distracted when using a cell phone than when talking to a passenger in the car? In a study involving 48 people, 24 people were randomly assigned to drive in a driving simulator while using a cell phone. The remaining 24 were assigned to drive in the driving simulator while talking to a passenger in the simulator. Part of the driving simulation for both groups involved asking drivers to exit the freeway at a particular exit. In the study, 7 of the 24 cell phone users missed the exit, while 2 of the 24 talking to a passenger missed the exit.

Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions Primary Question of Inference: If the treatment (cell phone vs. passenger) had no effect, is it possible that we would see this great a difference simply by chance (random assignment)?

50
Statistics Standards for Algebra II/Math III Making Inferences & Justifying Conclusions The simulation How might we use a deck of cards to represent the response: 9 people missing the exit (distracted) and 39 people who were not distracted? One possibility Distracted: A-9 clubs Not Distracted: Shuffle the cards and deal them into two piles. The first pile will be the cell phone treatment group. The second pile is the passenger treatment group. Count the number of clubs in each group. This represents the number of people who missed the exit (distracted drivers) that occur by chance. Each group repeats 9 more times.

(2007 NCSSM Summer Statistics Writing Program Permission given by Roxy Peck to share with Illinois Math Teachers In the original experiment 7 members of the cell phone group were distracted and missed the exit. In the simulation, how often “just by chance” did the cell phone group have 7 or more distracted drivers? With random reassignment, 6.8% of the cell phone group missed the exit 7 or more times.

Statistics Standards for Algebra I/Math I Interpreting Scatterplots Below is a graph of the heights and weights of currently rostered Chicago Bears (April 2014). Which is the best interpretation of the scatterplot? A. As heights go up, weight increases. B. As heights go up, weight tends to increase. C. If you get taller, you will get heavier. D. Taller football players tend to be heavier football players.

59
Statistics Standards for Algebra I/Math I Assessing the Fit of a Linear Function To assess the fit of a linear function to a scatterplot consider all of the following: 1. Look at the scatterplot. Does the data appear linear? 2. Look at r-value. What is the strength of the linear relationship between x and y? 3. Look at the residuals. Are they scattered with no discernable pattern?

60
When interpreting the correlation coefficient there are FOUR things that should be discussed: 1. The strength of the linear relationship: strong, moderate, weak, or no linear relationship. Statistics Standards for Algebra I/Math I Correlation

61
2. Whether the relationship between x and y is positive or negative. If the slope of the best fit line is positive, then the r value is also positive. If the slope of the best fit line is negative, then the r value is negative. Statistics Standards for Algebra I/Math I Correlation

62
3. The relationship we are evaluating is a linear relationship between x and y. For example, the two graphs below show a relationship between x and y that is something other than linear. Statistics Standards for Algebra I/Math I Correlation

63
4. CONTEXT! Be sure to interpret the correlation coefficient in the context of the problem. The linear association is between what two variables? Interpretation: r = 0.7 There is a moderate, positive linear relationship between the height (in inches) and the weight (in pounds) for the currently rostered Chicago Bears.

Statistics Standards for Algebra I/Math I Residuals The residual is the vertical distance from the data point to the line of best fit. Residual = Actual – Predicted Residual = 28 – 21 Residual = 7 (5, 28) actual (5, 21) predicted

66
Statistics Standards for Algebra I/Math I Residuals To create a residual plot, graph each x-coordinate with its corresponding residual. (x-value, residual) (5, 7) Residual = 7 This horizontal axis corresponds to the regression line. (x-value, residual)

68
Statistics Standards for Algebra I/Math I Residuals Why do we need to look at residual plots? Here is an example from Engage NY: The temperature (in degrees Fahrenheit) was measured at various altitudes (in thousands of feet) above Los Angeles. The scatter plot (next slide) seems to show a linear (straight line) relationship between these two quantities.

Statistics Standards for Algebra II/Math II Conditional Probability and the Rules of Probability Big Ideas Provide opportunities for students to independently determine if a problem is asking for an AND, OR, or conditional probability. Provide data from real life problems. Ask students to calculate probabilities and interpret probabilities in the context of the problem. Students should be able to create and interpret two-way frequency tables, diagrams, probability trees, and other graphical displays. Determine if two events are independent or dependent, and interpret what this means in the context of the problem.

77
Examples of events which are likely to be dependent: The event that a student spends more time on homework and studying and the event that the student’s test average goes up. The event that the amount of snow is above average in a given winter and the event that the number of show shovel sales is also above average for that winter. The event that a randomly selected passenger on the Titanic was a woman and the event that the passenger survived. Example of events which are independent The event that a 2 is rolled on the first roll of a dice and the event that a 2 is rolled on a second roll of a dice. The event that a couple’s first child is a boy and the event that a couple’s second child is a girl.
