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 displays its minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

Front

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

Back

The median represents 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: Q1 (25th percentile), Q2 (50th percentile or median), and Q3 (75th percentile).

Front

How do you find the range of a data set?

Back

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

Front

What does Q1 represent in a Box and Whisker Plot?

Back

Q1 represents the first quartile, which is the median of the lower half of the data set.

Front

What does Q3 represent in a Box and Whisker Plot?

Back

Q3 represents the third quartile, which is the median of the upper half of the data set.

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 the whisker in a Box and Whisker Plot indicate?

Back

The whiskers indicate the range of the data, extending from the minimum to Q1 and from Q3 to the maximum.

Front

How can you determine if a data set is skewed using a Box and Whisker Plot?

Back

If the median line is closer to Q1 or Q3, the data set is skewed. If it is centered, the data set is symmetric.

Front

What is the minimum value in a Box and Whisker Plot?

Back

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