Question

the area shaded gray in the boxplot is the *
interquartile range
mean
median
mode
outlier
standard deviation

Explanation:

In a boxplot, the box represents the interquartile range (IQR). The IQR is the range between the first quartile ($Q_1$) and the third quartile ($Q_3$), which contains the middle 50% of the data. The median is shown as a line within the box, not the shaded area. The mean, mode, and standard deviation are not directly represented by the box (shaded area) in a boxplot. Outliers are shown as individual points outside the whiskers of the boxplot.

Answer:

interquartile range
