Here are the math test scores of 10 randomly selected students. 83, 85, 91, 93, 72, 85, 76, 80, 82, 89. Find the mean score

Answer 1

To find the mean score, we need to add up all the scores and then divide by the total number of scores.

Adding up all the scores:
83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89 = 846

Now we divide by the total number of scores, which is 10:
Mean score = 846 / 10 = 84.6

Therefore, the mean score of the 10 randomly selected students is 84.6.
