Answer :
b. Mean: 82.2 Median: 78 Mode: 69
Mean: To find the mean, add all the scores together and divide by the number of scores.
- Sum = 99 + 69 + 96 + 69 + 78 = 411
- Number of scores = 5
- Mean = 411 / 5 = 82.2
Median: To find the median, list the scores in numerical order and find the middle number.
- Ordered scores = 69, 69, 78, 96, 99
- Median (middle score) = 78
Mode: The mode is the score that appears most frequently.
- Mode = 69 (appears twice)
