Mean: To find the mean, we add up all the numbers and divide by the total number of scores.
83 + 85 + 82 + 93 + 83 + 84 + 95 + 87 + 86 + 94 = 872
872/10 = 87.2
The mean score is 87.2.
Median: To find the median, we need to put the scores in order from lowest to highest.
82, 83, 83, 84, 85, 86, 87, 93, 94, 95
There are 10 scores, so the median will be the average of the fifth and sixth scores.
Median = (85 + 86)/2 = 85.5
The median score is 85.5.
Mode: The mode is the score that appears most frequently. In this case, there are two scores that appear twice (83).
Therefore, the mode is 83.
Test scores for a math class are shown below.
83,85,82,93,83,84,95,87,86,94
