Creating Box and Whisker Plots

In this video, Mr. Jay explains how to create box and whisker plots, also known as box plots, to visually represent data and its spread. The tutorial covers ordering data, identifying the minimum and maximum values, calculating the median, and determining the first and third quartiles. Finally, it demonstrates how to construct a box and whisker plot using these values, providing a clear visual representation of the dataset.

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

• To calculate the mean of a dataset

• To determine the mode of the data

• To display data and its spread visually

• To plot the data on a bar graph

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

• Drawing the number line

• Calculating the mean

• Ordering the data from least to greatest

• Finding the median

How is the median of a dataset determined when the dataset has an even number of entries?

• By averaging the two middle numbers

• By choosing the smallest number

• By taking the middle value

• By selecting the largest number

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

• The median of the lower half of the data

• The minimum value of the dataset

• The median of the upper half of the data

• The maximum value of the dataset

Where is the third quartile located in a box and whisker plot?

• At the end of the box

• Between the median and the maximum

• Between the minimum and the median

• At the start of the box

What is the correct sequence to plot the elements in a box and whisker plot?

• Maximum, third quartile, median, first quartile, minimum

• Median, first quartile, third quartile, minimum, maximum

• First quartile, third quartile, median, minimum, maximum

• Minimum, first quartile, median, third quartile, maximum

What is the role of whiskers in a box and whisker plot?

• To indicate the mean of the data

• To show the range from minimum to maximum

• To display the mode of the dataset

• To represent the median value

How do you determine the position of the median line within the box?

• It is placed at the third quartile

• It is placed at the maximum value

• It is placed at the first quartile

• It is placed between the first and third quartiles

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

• The end of the upper whisker

• The start of the lower whisker

• The beginning of the first quartile

• The middle of the box

Which of the following is not a component of a box and whisker plot?

• Median

• Third quartile

• First quartile

• Mean
