Exploring Box Plots in 7th Grade Math

The video tutorial explains how to create a box and whisker plot. It begins with ordering data, finding the median, and creating a number line. The tutorial then covers identifying quartiles, understanding whiskers, and recognizing outliers. An example with a new data set is provided, followed by a review and conclusion of the lesson.

What is the first step in creating a box and whisker plot?

• Finding the median

• Organizing the data in order

• Drawing the whiskers

• Identifying outliers

What value is used as the median in the first example?

• 27

• 28

• 25

• 26

What does the lower quartile represent in a box and whisker plot?

• The median of the lower half of the data

• The highest value in the data set

• The lowest value in the data set

• An outlier in the data set

How are outliers represented in a box and whisker plot?

• With a line

• With an asterisk

• With a whisker

• With a box

What does the box in a box and whisker plot represent?

• The range of the data

• The interquartile range

• The total spread of the data

• The median of the data

How is the upper quartile determined in a box and whisker plot?

• It is the median of the upper half of the data

• It is the highest value in the data set

• It is the same as the lower quartile

• It is the average of all data points

What is the median of the new data set introduced?

• 65

• 60

• 70

• 42

What is the range of the new data set?

• 65-100

• 35

• 100

• 65

Which of the following is NOT a step in creating a box and whisker plot?

• Identifying the lower quartile

• Finding the median

• Drawing the whiskers

• Calculating the mean

What is the purpose of a box and whisker plot?

• To calculate the sum of the data

• To identify the mean of the data

• To show the distribution of the data

• To find the maximum value only
