Mean: To find the mean, we add up all the scores and divide by the total number of scores.
83 + 85 + 82 + 93 + 83 + 84 + 95 + 87 + 86 + 94 = 872
Mean = 872/10 = 87.2
Median: To find the median, we need to find the middle value when the scores are listed in order.
82, 83, 83, 84, 85, 86, 87, 93, 94, 95
The median is 85.5, which is the average of the middle two values (85 and 86).
Mode: The mode is the score that appears most frequently in the data set. In this case, there are two values that appear twice (83 and 94), while all other scores only appear once. Therefore, there is no single mode for this data set.
the test scores for a math class are shown below. 83, 85, 82, 93, 83, 84, 95, 87, 86, 94 what are the mean, median and mod of the data set?
