Question

If the outliers are not included, what is the mean of the data set? 76, 79, 80, 82, 50, 78, 83, 79, 81, 82 (2 points) Select one: a. 77 b. 78 c. 79 d. 80

Answer 1

Hello!

As you can see, 50 is the outlier, as it is not around the other numbers in the data set. Therefore, we will calculate the mean of all the numbers if we add up all the numbers and divide by 9.

(76+79+80+82+78+83+79+81+82)÷9=80

The mean of this data set (excluding the outlier) is 80.

I hope this helps!
