Question

The first quartile of the data set represented by the box plot is (8, 9, 12,14) . The median of the data set is (8, 12,16,19)

Answer 1

The first quartile is 12. The median is 16!

Answer 2

Answer: 16

Step-by-step explanation:

• The median is the middle number of a set of data  (if there are an odd number of data values) or the average of the two middle numbers (if there are an even number of data values).

• A  box-whisker plot gives us information of the shape, variability, and median of a data set.

From the given box-whisker plot a vertical line goes through the box at 16 i.e. the median.

Hence, the median of the data set = 16.
