Question

Find the mean of :6.8, 15.4, 21.6, 19.2, 12.5, 13.2, 16.3

Answer 1

Answer:

15

Step-by-step explanation:

Since we know that the mean of ungrouped data is: Sum of all the observations divided by Total Observations,

Mean = (6.8 + 15.4 + 21.6 + 19.2 + 12.5 + 13.2 + 16.3) divided by 7

          = 105 divided by 7

          = 15

Thus the mean of the given data is 15.
