Analyzing Stem and Leaf Plots

This video tutorial explains how to create and interpret a back-to-back stem-and-leaf plot to compare two data sets, specifically male and female data. The tutorial covers setting up the plot, analyzing data for each group, and making comparative statements based on the distribution of scores.

What is the primary purpose of a back-to-back stem and leaf plot?

• To calculate the average of a data set

• To display a single set of data

• To find the median of a data set

• To compare two different sets of data simultaneously

In a back-to-back stem and leaf plot, where is the stem located?

• At the top

• In the middle

• On the right side

• On the left side

When setting up the plot, which data set is placed on the left side?

• Neither

• Both

• Females

• Males

What is the smallest number in the female data set?

• 48

• 86

• 42

• 91

What is the largest number in the male data set?

• 48

• 86

• 91

• 42

What is the first step in creating a back-to-back stem and leaf plot?

• Compare the data sets

• List all data points

• Draw the stem

• Identify the smallest and largest numbers

What is the largest number in the female data set?

• 42

• 91

• 86

• 48

How is the number 42 represented in the stem and leaf plot?

• 24

• 4 | 2

• 2 | 4

• 42

Which number is not part of the male data set?

• 48

• 59

• 66

• 91

What is the correct order of numbers in the 70s for the male data set?

• 72, 71, 74

• 71, 74, 72

• 71, 72, 74

• 74, 72, 71
