Understanding Box and Whisker Plots

Ms. Wendell introduces box and whisker plots, explaining their components and vocabulary. She provides examples and guides students through calculating and drawing these plots. The video also covers identifying outliers and includes practice exercises to reinforce learning.

What is the primary focus of the lesson introduced by Ms. Wendell?

• Learning about pie charts

• Exploring line graphs

• Understanding box and whisker plots

• Studying bar graphs

Which term refers to the smallest number in a data set?

• Median

• Upper extreme

• Upper quartile

• Lower extreme

What is the median in a box and whisker plot?

• The average of the data set

• The lowest data point

• The middle value of the data set

• The highest data point

How do you find the interquartile range (IQR)?

• Subtract the lower quartile from the upper quartile

• Add the lower quartile to the upper quartile

• Subtract the minimum from the maximum

• Divide the maximum by the minimum

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

• Identify the outliers

• Draw the number line

• Order the data from least to greatest

• Calculate the mean

In the example with the baseball team, what was the median of the data set?

• 5

• 8

• 9

• 12

What does a long whisker in a box and whisker plot indicate?

• A small range

• A high median

• A large data set

• An outlier

How can you mathematically determine if a data point is an outlier?

• By checking if it is the median

• By comparing it to the mean

• By using the interquartile range and a factor of 1.5

• By finding the range

What is the purpose of drawing a number line when creating a box and whisker plot?

• To calculate the mean

• To identify the mode

• To find the standard deviation

• To plot the data points and quartiles

What should students do after watching the video tutorial?

• Memorize the definitions

• Create a pie chart

• Complete an assignment

• Write a report
