Understanding Box and Whisker Plots

The video tutorial by Mr. Jay explains how to create a box and whisker plot, also known as a box plot. It begins with an introduction to the concept and purpose of box plots, followed by organizing data from least to greatest. The tutorial then covers finding the minimum, maximum, median, and quartiles. Finally, it demonstrates how to create the box and whisker plot and provides tips for finalizing the plot.

What is the primary purpose of a box and whisker plot?

• To display the mean of a data set

• To find the range of a data set

• To show the spread and distribution of data

• To calculate the mode of a data set

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

• Organizing data from least to greatest

• Calculating the mean

• Identifying the mode

• Finding the median

Which of the following is NOT a key data point in a box and whisker plot?

• Minimum

• Median

• Mean

• Third Quartile

How is the median determined in a data set with an odd number of values?

• It is the smallest number

• It is the middle number

• It is the average of the two middle numbers

• It is the largest number

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

• The 50th percentile

• The 25th percentile

• The 100th percentile

• The 75th percentile

What is the purpose of the number line in a box and whisker plot?

• To display the mean

• To show the range of data

• To calculate the mode

• To mark the quartiles and median

Where do the whiskers extend to in a box and whisker plot?

• To the mean and mode

• To the first and third quartiles

• To the minimum and maximum

• To the median and mode

What is the significance of the median line inside the box?

• It indicates the median

• It shows the mode

• It marks the range

• It represents the mean

What should you use to ensure straight lines when drawing a box and whisker plot by hand?

• A ruler

• A compass

• A calculator

• A protractor

What is the final step in completing a box and whisker plot?

• Finding the mode

• Extending the whiskers

• Drawing the box

• Calculating the mean
