Monday: BELL WORK *SHOW WORK  Use notebook paper and create the bell work grid  Make sure you put the correct letter DateWorkAnswer 3/16 3/17 3/18 3/20 * show work- do not just write down an answer Ramona scored 84% on her math test. Bryan correctly answered _ 4/5 of the test questions. Tori scored 44 out of 50. Rance completed 0.86 of the questions correctly. Each test question is worth the same amount. Who has the best score? F Ramona G Bryan H Tori J Rance

Tuesday: BELL WORK *SHOW WORK * show work- do not just write down an answer The area of a square field is 14,400 square feet, as shown below. What is the length of one side of the field? A = 14,400 ft2. F 100 feet G 110 feet H 112 feet J 120 feet

AGENDA 1- bell work 1- bell work 2- Agenda- 2- Agenda- Homework WB p. 60 Homework WB p. 60 project due 3/25 project due 3/25 3- Objective 4- lesson – MMMR (measures of central tendency) and Box & Whisker Plots 4- lesson – MMMR (measures of central tendency) and Box & Whisker Plots 5- exit ticket 5- exit ticket

OBJECTIVE  SPI 0706.5.3 Calculate and interpret the mean, median, upper-quartile, lower-quartile, and interquartile range of a set of data.

Measures of Central Tendency Median Value The Median is the "middle number" (in a sorted list of numbers). To find the Median, place the numbers in value order and find the middle number. Mean The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. Mode To find the mode, or modal value, first put the numbers in order, then count how many of each number. A number that appears most often is the mode. If all numbers appear an equal amount then there is no mode. Range The Range is the difference between the lowest and highest values. To find it subtract the Largest #- smallest #

Median examples

Mean examples

Mode examples Example: 1, 2, 4, 8, 9, 10, 12 No mode- **if all appear an equal number of times

Range examples

EXIT TICKET  Discuss with your partner Discuss the 4 measures of central tendency and what each one means.

Wednesday: BELL WORK *SHOW WORK * show work- do not just write down an answer

AGENDA 1- bell work 1- bell work 2- Agenda- project due 3/25 2- Agenda- project due 3/25 Workbook p. 63 Workbook p. 63 3- Objective 4- lesson – MMMR (measures of central tendency) and Box & Whisker Plots 4- lesson – MMMR (measures of central tendency) and Box & Whisker Plots 5- exit ticket 5- exit ticket

OBJECTIVE  SPI 0706.5.3 Calculate and interpret the mean, median, upper-quartile, lower-quartile, and interquartile range of a set of data.

Box and Whisker Plots Box and whisker plot is a way of displaying data. It has 5 parts. Lower extreme (lowest number in the data set) Lower quartile (1 st quartile) (median of the “lower” numbers) Median (2 nd quartile) (middle number of the data set) Upper quartile (3 rd quartile) median of the “upper” numbers) Upper extreme (highest number in the data set)

To find the quartiles

Look at what happens when you have to find the mean for your median

Range vs Interquartile Range  Range looks at the whole data Largest – smallest = range Interquartile Range looks at the data in the box Upper quartile – lowest quartile = interquartile range

EXIT TICKET  Discuss with your partner Which measure of central tendency do you use the most for box and whisker plots?

Thursday: BELL WORK Have a pencil and calculator on your desk. N2K Critical Thinking: Solve for the measures of central tendency and see which one is 12.2. Show work for all. CR: Using the table answer the questions about the data. When done- turn in and work on project

Friday: BELL WORK *SHOW WORK * show work- do not just write down an answer Turn in bell work today when you are done
