Given the following set of numbers: 85, 100, 90, 95, 80;

1). Show each step on how to calculate the arithmetic meanfor the five numbers

2). Show each step on how to obtain the absolute value of each of the five deviation scores and show me how to sum them.

3) Divide the sum of the deviation scores by the number of measurements (5).

1. Show each step on how to calculate the arithmetic mean for the five numbers.

Arithmetic mean = (85 + 100 + 90 + 95 + 80)/5 …

This solution shows the steps to find the arithmetic mean, absolute values, and sum of five deviation scores.
