Question

Calculate the MEAN for the data set: 6, 7, 12, 8, 7, 4, 8, 8, 7.

Round to the nearest hundredth

Answer 1

Take the sum of the values, then divide by the number of values.

Sum of values = 6+7+12+8+7+4+8+8+7=67
Number of values = 9
Mean = 67/9 = 7.44

Answer 2

7.44

Explanation:

To find the mean, we first need to add up all the terms.

6 + 7 + 12 + 8 + 7 + 4 + 8 + 8 + 7

67

Now, we divide this number by the amount of terms there are, which is 9.

67 / 9 = 7.44444444444

Round this to the nearest hundredth and we arrive at 7.44
