Question

What is the mean of the data set?

125, 141, 213, 155, 281


126.80
158.00
183.00
228.75

Answer 1

183

Explanation:

125+141+213+155+281=915

915 divided by 5=183

Answer 2

The mean of data set = 183

Explanation:

Formula:

Mean of a data set is given by,

Mean = (sum of all data set)/(total number of data set)

To find total sum of data set

Here data set is,

125, 141, 213, 155, 281

Sum = (125 + 141 + 213 + 155 + 281) = 915

To find the mean of data set

Total sum = 915 and total number = 5

Mean = (sum of all data set)/(total number of data set)

Mean = 915/5 = 183

Therefore mean of data set = 183
