Question

A student earned the scores in the data set in one course. {78, 64, 74, 92, 67} What is the mean of the scores?

Answer 1

Answer: The mean is 75

Explanation:

- You add the scores in the data:

78+64+74+92+67 = 375

- Then divide by the number of scores in the data:

there are 5 scores in the data,

1) 78

2) 64

3) 74

4) 92

5) 67

- So:

375/5 = 75 <--- mean

Answer 2

Answer: 75

To calculate mean or average from a data set, add all the data points together and then divide by the number of points you added together.
In this case,
78+64+74+92+67= 375/5= 75
