Question

Miriam’s study group received test scores of 96, 81, 82, 99, 94, 92, 95, 82, and 80. Find the mean and median scores.

Answer 1

Answer:

The mean is  

✔ 89

The median is  

✔ 92

Answer 2

The mean of Miriam's test scores is 89 and the median is 92.

What is mean?

"It is the average of a data set. "

What is median?

"It is the middle value in a list ordered from smallest to largest."

For given question,

Total number of test scores = 9

The sum of all the test scores would be,

96 + 81 + 82 + 99 + 94 + 92 + 95 + 82 + 80 = 801

So, the mean would be,

$\bar{X}=\frac{801}{9} \\\\\bar{X}=89$

So, the mean of Miriam's test scores is 89.

If we arrange the test scores in ascending order then it would be,

80, 81, 82, 82, 92, 94, 95, 96, 99

The middle value is 92

So, the median is 92.

Therefore, the mean of Miriam's test scores is 89 and the median is 92.
