How are descriptive statistics calculated?
To calculate descriptive statistics: Mean: Add up all the scores and divide by the number of scores.
Mean = (85 + 90 + 75 + 92 + 88 + 79 + 83 + 95 + 87 + 91 + 78 + 86 + 89 + 94 + 82 + 80 + 84 + 93 + 88 + 81) / 20 = 1770 / 20 = 88.5.
Median: Arrange the scores in ascending order and find the middle value.Oct 19, 2023.
