Exploring Box and Whisker Plots

This video tutorial covers the concept of box and whisker plots, a method for displaying data. It explains the components of the plot, including the median, quartiles, and extremes, and how data is divided into four parts. The tutorial provides examples using Yankees Stadium attendance and pitch speeds of baseball teams. It also includes a step-by-step guide on creating a box and whisker plot, emphasizing the importance of organizing data and calculating medians and quartiles.

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

• The highest value of the dataset

• The middle value of the dataset

• The lowest value of the dataset

• The average value of the dataset

What does the upper quartile represent?

• The median of the lower half of the dataset

• The median of the upper half of the dataset

• The highest value of the dataset

• The lowest value of the dataset

What percentage of data falls within the interquartile range of a box and whisker plot?

• 25%

• 50%

• 75%

• 100%

How many people attended the game with the least amount of fans, according to the box plot?

• 50,000

• 34,000

• 40,000

• 45,000

What is the range of the dataset if the lower extreme is 15 and the upper extreme is 80?

• 75

• 65

• 95

• 85

What was the median pitching speed for the Cubs?

• 92 mph

• 97 mph

• 93 mph

• 95 mph

Which team had a faster pitching speed according to the box and whisker plot?

• Cubs

• Athletics

• Data is inconclusive

• Both had the same speed

How is the interquartile range calculated?

• Upper extreme minus lower extreme

• Upper quartile plus lower quartile

• Upper quartile minus lower quartile

• Median minus lower quartile

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

• Drawing the box

• Calculating the interquartile range

• Organizing the data from smallest to largest

• Finding the median

What does the lower extreme indicate in a box and whisker plot?

• The highest value

• The lowest value

• The average value

• The median value
