Question

Suppose that there are 20 numbers in a data set and that they are all different. How many of the values in this data set are between the first quartile and the median?

Answer 1

The answer for this one is 4

Answer 2

4

Explanation:

Since the first quartile is at 25%, 25% of 20 is 5. The median is the 50% mark of the set, and 50% of 20 is 10. So, there are 4 numbers between the 5th data point and the 10th, which are the 6th,7th,8th, and 9th data points.
