Question

find the mean of 9, 9, 2, 9, 1 graphically.
9 + 9 + 2 + 9 + 1 = 30
average = $\frac{30}{5}$ = 6
type the values 9, 9, 2, 9, 1 into the input boxes at the bottom of the graph.

Explanation:

Step1: Calculate sum of numbers

$9 + 9+2 + 9+1=30$

Step2: Divide sum by count

The count of numbers is 5. So, $\frac{30}{5}=6$
