Question

What is the first quartile, Q1, of the following distribution?

24, 26, 26, 26, 27, 31, 33, 35, 37, 38, 40, 42, 43, 46, 48, 55, 56

Answer 1

26.5

Explanation:

the median is 37 due to there being 17 data points in the set. So the first quartile wouldn't contain 37 so you find the other point. The point is in between 26 and 27, so you add those 2 points together and divide it by 2 to get your answer.
