Understanding Box Plots Concepts

The video tutorial provides a guided practice for lesson 10.2, focusing on understanding and analyzing box plots. It covers key concepts such as identifying minimum and maximum values, calculating the median, and understanding quartiles. The tutorial also explains how to calculate the range and interquartile range, and how to use these metrics to compare data sets, specifically in the context of hockey and volleyball players. The video concludes with a discussion on using box plots for effective data comparison.

What is the main focus of the guided practice in lesson 10.2?

• Understanding algebraic expressions

• Learning about box plots

• Exploring probability

• Studying geometric shapes

In a box plot, where is the minimum value located?

• At the center of the box

• At the end of the whisker

• At the bottom of the box

• At the top of the box

What is the maximum value in a box plot?

• The value at the end of the whisker

• The value at the center of the box

• The value at the top of the box

• The value at the start of the whisker

How is the median represented in a box plot?

• As the end of the whisker

• As the line inside the box

• As the bottom of the box

• As the top of the box

What are the lower and upper quartiles in a box plot?

• The values at the ends of the box

• The lines inside the box

• The start and end of the whiskers

• The top and bottom of the box

How do you calculate the range in a box plot?

• Subtract the median from the maximum

• Subtract the minimum from the maximum

• Subtract the minimum from the median

• Subtract the lower quartile from the upper quartile

What is the interquartile range (IQR)?

• The sum of the quartiles

• The average of the quartiles

• The difference between the maximum and minimum

• The difference between the upper and lower quartiles

Which group has a greater median: hockey or volleyball players?

• Cannot be determined

• Both have the same median

• Volleyball players

• Hockey players

Which group has the shortest player based on the box plot?

• Hockey players

• Cannot be determined

• Volleyball players

• Both have the same shortest player

What is the interquartile range for both groups?

• 20

• 5

• 10

• 15
