Box and Whisker Plots

Front

What is a Box and Whisker Plot?

Back

A Box and Whisker Plot is a graphical representation of a data set that shows its minimum, lower quartile, median, upper quartile, and maximum.

Front

What does the median represent in a Box and Whisker Plot?

Back

The median is the middle value of a data set when it is ordered from least to greatest.

Front

What are quartiles in a Box and Whisker Plot?

Back

Quartiles are values that divide a data set into four equal parts. The lower quartile (Q1) is the median of the lower half, and the upper quartile (Q3) is the median of the upper half.

Front

How do you find the interquartile range (IQR)?

Back

The interquartile range (IQR) is found by subtracting the lower quartile (Q1) from the upper quartile (Q3): IQR = Q3 - Q1.

Front

What does the minimum value represent in a Box and Whisker Plot?

Back

The minimum value is the smallest number in the data set.

Front

What does the maximum value represent in a Box and Whisker Plot?

Back

The maximum value is the largest number in the data set.

Front

How can you identify the median from a Box and Whisker Plot?

Back

The median is represented by the line inside the box of the Box and Whisker Plot.

Front

What is the purpose of a Box and Whisker Plot?

Back

The purpose of a Box and Whisker Plot is to visually summarize the distribution of a data set and identify its central tendency and variability.

Front

What does a wider box in a Box and Whisker Plot indicate?

Back

A wider box indicates a larger interquartile range (IQR), meaning there is more variability in the middle 50% of the data.

Front

What does a narrow box in a Box and Whisker Plot indicate?

Back

A narrow box indicates a smaller interquartile range (IQR), meaning there is less variability in the middle 50% of the data.
