What is a Box and Whisker Plot?

Back

A Box and Whisker Plot is a graphical representation of a dataset that displays its minimum, first quartile, median, third quartile, and maximum.

Front

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

Back

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

Front

What are quartiles in a Box and Whisker 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.

Front

How do you find the first quartile (Q1)?

Back

To find Q1, order the data set and find the median of the lower half of the data.

Front

How do you find the third quartile (Q3)?

Back

To find Q3, order the data set and find the median of the upper half of the data.

Front

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

Back

The whiskers extend from the quartiles to the minimum and maximum values, showing the range of the data.

Front

What is the purpose of a Box and Whisker Plot?

Back

The purpose is to visually summarize the distribution of a dataset, highlighting its central tendency and variability.

Front

How can you determine the interquartile range (IQR) from a Box and Whisker Plot?

Back

The interquartile range (IQR) is calculated as Q3 - Q1, representing the range of the middle 50% of the data.

Front

What does a longer whisker indicate in a Box and Whisker Plot?

Back

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

Front

What does point C represent in a Box and Whisker Plot?

Back

Point C represents the median of the dataset.
