If the heights of 4 family members is 153, 150, 151 and 152, find the mean height of the family.

151.5

Step-by-step explanation:

First of all, what is the mean in a set of numbers?

The mean is the average of all the numbers in the set. We can find this by finding the total value of all the terms and then dividing it by the number of terms. Let's just do a short example so we can make sure you understand. Let's look at this set of numbers:5, 3, 7, 4.

To find the average of these numbers, we'll add all of the numbers and divide it by 4, the number of actual terms, in the set.

(5 + 3 + 7 + 4) / 4 = 19/4 which is also 4.75. Back to the actual problem.

(153 + 150 + 151 + 152) / 4 = 151.5

Answer: 151.1

Step-by-step explanation:

First, you would add all the heights together (153+150+151+152=606)

Then you would divide 606 by the number of numbers in the data set in this case the number of family members which is (606 divided by 4 = 151.1)
