Box Plots

Front

What is a box plot?

Back

A box plot, also known as a whisker plot, is a graphical representation of a dataset that shows its minimum, first quartile, median, third quartile, and maximum.

Front

What does the median represent in a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. It divides the dataset into two equal halves.

Front

How do you find the range of a dataset?

Back

The range is found by subtracting the minimum value from the maximum value in the dataset.

Front

What are quartiles in a box plot?

Back

Quartiles are values that divide a dataset into four equal parts. The first quartile (Q1) is the median of the lower half, the second quartile (Q2) is the median, and the third quartile (Q3) is the median of the upper half.

What does the whisker in a box plot represent?

Back

The whiskers in a box plot extend from the quartiles to the minimum and maximum values, showing the spread of the data.

Front

How can you identify the median from a box plot?

Back

The median is represented by the line inside the box of the box plot.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.

Front

How do you compare medians from two box plots?

Back

You can compare the median lines in the boxes of the two plots; the higher line indicates a higher median.

Front

What does a longer whisker indicate in a box plot?

Back

A longer whisker indicates a greater spread or variability in the data.
