Find:

  • The mean of the given data set.

Solution:

A mean is the average of a data set.

We find the mean by adding all numbers together and then dividing the sum of the numbers by the number of numbers.

Now, a summation of number = 2+4+4+7+2+6+7+4+8+2+3+6+9+4+7 = 75

Now, there are total of 15 data given.

Therefore, mean = 75/15 = 5.
