Find the median score.


​

Answer 1

Answer:

The median is 24.

Step-by-step explanation:

The median of a data set is the middle value of that data set.

The data set provided in ascending order is:

17, 19, 19, 20, 21, 22, 23, 24, 25, 26, 29, 31, 35, 40

As the data set consist of odd number of values, the median will be computed using the formula:

$Median =[\frac{n+1}{2}]^{th}\ observtaion$

Compute the median observation as follows:

$Median =[\frac{15+1}{2}]^{th}\ observtaion =8^{th}\ observtaion$

The median is the 8th observation.

The 8th observation is 24.

Thus, the median is 24.
