Flashcard-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, first quartile, median, third quartile, and maximum values.

Front

What does the maximum value represent in a data set?

Back

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

Front

What does the minimum value represent in a data set?

Back

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

Front

What are quartiles in a box and whisker plot?

Back

Quartiles are values that divide a data set 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 median of a data set?

Back

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

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, highlighting its central tendency and variability.

Front

What does the whisker represent in a box and whisker plot?

Back

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

Front

What is the range of a data set?

Back

The range is the difference between the maximum and minimum values in a data set.

Front

How can you identify outliers in a box and whisker plot?

Back

Outliers can be identified as points that fall outside the whiskers of the box and whisker plot, typically more than 1.5 times the interquartile range (IQR) from the quartiles.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1), representing the middle 50% of the data.
