Find the median, first quartile, third quartile, and interquartile range of the data.

14,25,97,55,66,28,92,38,94

Answer 1

Median: 55, first quartile: 26.5, third quartile: 93, interquartile: 66.5

Answer 2

BELOW IN BOLD.

Explanation:

14,25,97,55,66,28,92,38,94

Arrange these in ascending order:

= 14 25 28 38 55 66 92 94 97

The median = middle number = 55.

First quartile = (25+28)/2 = 26.5.

Third quartile = (92 + 94)/2 = 93.

Interquartile range = 93 - 26.5 = 66.5.
