StandardState Performance Indicator Basic Algebra Skills*Solve Multistep single variable equation Analyze Statistical Data* SPI 3103.5.1 Compute, compare and explain summary statistics for distributions of data including measures of center and spread. SPI 3103.5.2 Compare data sets using graphs and summary statistics. Use Linear Regression to analyze Scatter Plots* SPI 3103.5.3 Analyze patterns in a scatter-plot and describe relationships in both linear and non-linear data. SPI 3103.5.6 Find the regression curve that best fits both linear and non-linear data (using technology such as a graphing calculator) and use it to make predictions. SPI 3103.5.7 Determine/recognize when the correlation coefficient measures goodness of fit. Identify Interquartile RangeSPI 3103.5.4 Apply the characteristics of the normal distribution. Recognize Random vs Observed Experiments SPI 3103.5.5 Determine differences between randomized experiments and observational studies. Recognize Data Bias SPI 3103.1.2 Recognize and describe errors in data collection and analysis as well as identifying representations of data as being accurate or misleading. Identify Domain, Range and Restrictions (Linear Function)* SPI 3103.3.5 Describe the domain and range of functions and articulate restrictions imposed either by the operations or by the contextual situations which the functions represent. Evaluate Arithmetic Sequences* SPI 3103.3.4 Use the formulas for the general term and summation of finite arithmetic and both finite and infinite geometric series.

11. Survey Design SPORTS Which question will determine the most popular spectator sport? A. Isn’t football an exciting sport to watch? Answer: This question is biased in favor of tennis. B. What is your favorite sport to watch? Answer:This question is biased in favor of football. Answer: This is an unbiased question that will produce the answer being sought. C. Do you like to watch tennis matches?

12. A.Do you prefer milk chocolate or dark chocolate? B.Do you like to put ice cream on top of a piece of apple pie? C.What is your favorite dessert to eat? D.None of these DESSERT Will this question determine the most popular dessert? Which question is best to determine the most popular dessert?

13. A.experiment; treatment group: students who play sports; control group: students who do not play sports; biased B.experiment; treatment group: students who do not play sports; control group: students who play sports C.experiment; treatment group: students who do not play sports; control group: students who play sports; not biased D.observational study; treatment group: students who play sports; control group: students who do not play sports A. EXPERIMENT State whether the example represents an experiment or an observational study. If it is an experiment, identify the control group and the treatment group. Then determine whether there is a bias. Find 100 students, half of whom play sports after school. Compare their number of siblings.

14. A.experiment; treatment group: students who eat breakfast; control group: students who do not eat breakfast; biased B.experiment; treatment group: students who do not eat breakfast; control group: students who eat breakfast C.experiment; treatment group: students who do not eat breakfast; control group: students who eat breakfast; not biased D.observational study; treatment group: students who eat breakfast; control group: students who do not eat breakfast B. EXPERIMENT State whether the example represents an experiment or an observational study. If it is an experiment, identify the control group and the treatment group. Then determine whether there is a bias. Find 100 students and randomly split them into two groups. One group eats breakfast and the other group does not.
