In constructing a box-and-whisker plot from a data set, which values are at the ends of the box? a. the mean and median b. the minimum and maximum c. the first and third quartiles d. the mode and range

 In constructing a box-and-whisker plot from a data set,  the minimum and maximum values are at the ends of the box.

Step-by-step explanation:

A box and whisker plot displays the five measures of data. The five measures summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile.

Therefore, In constructing a box-and-whisker plot from a data set,  the minimum and maximum values are at the ends of the box.

Hence, A is the right option,
