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

Front

What is the maximum value in a box plot?

Back

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

What is the median in a box plot?

Back

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

What are quartiles in a box plot?

Back

Quartiles divide the data set into four equal parts: the first quartile (Q1), median (Q2), and third quartile (Q3).

Front

What is the first quartile (Q1)?

Back

The first quartile (Q1) is the median of the lower half of the data set.

Front

What is the third quartile (Q3)?

Back

The third quartile (Q3) is the median of the upper half of the data set.

Front

How do you find the interquartile range (IQR)?

Back

The interquartile range (IQR) is found by subtracting the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

Front

What does a box plot show about data distribution?

Back

A box plot shows the spread and skewness of the data, highlighting outliers and the range.

Front

What is an outlier in a box plot?

Back

An outlier is a data point that is significantly higher or lower than the other data points in the set.
