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 lower quartile represent in a data set?

Back

The lower quartile (Q1) is the value that separates the lowest 25% of the data from the rest.

Front

How do you find the median of a data set?

Back

To find the median, arrange the data in ascending order and locate the middle value. If there is an even number of values, average the two middle values.

Front

What is the minimum value in a data set?

Back

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

Front

What is the maximum value in a data set?

Back

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

Front

What does the upper quartile represent in a data set?

Back

The upper quartile (Q3) is the value that separates the highest 25% of the data from the rest.

Front

How do you identify the range of a data set?

Back

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

Front

What is the purpose of a Box and Whisker Plot?

Back

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

Front

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

Back

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

Front

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

Back

If the median line in the box is closer to the lower or upper quartile, the data set is skewed in that direction.
