Box and Whisker, Stem and Leaf Review

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 (Q1), median, third quartile (Q3), and maximum.

Front

What does the median represent in a data set?

Back

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

Front

How do you find the maximum value in a data set?

Back

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

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 interquartile range (IQR)?

Back

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

Front

How do you calculate the interquartile range?

Back

Subtract Q1 from Q3: IQR = Q3 - Q1.

Front

What does Q1 represent in a Box and Whisker Plot?

Back

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

Front

What does Q3 represent in a Box and Whisker Plot?

Back

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

Front

What is the purpose of a Stem and Leaf Plot?

Back

A Stem and Leaf Plot is used to display quantitative data in a way that retains the original data while showing its distribution.

Front

How do you create a Stem and Leaf Plot?

Back

Separate each data point into a 'stem' (the leading digit(s)) and a 'leaf' (the trailing digit), then organize them in a table.
