How to find deviation

Answer 1

[AI-generated answer — Bot GPT 3.5]

The deviation can be calculated using the following steps:

1. Find the mean of the data set. Add up all the values in the set and divide by the total number of values. For example, if you have the set of numbers {5, 7, 9, 11, 13}, the mean would be (5 + 7 + 9 + 11 + 13) / 5 = 9.

2. Subtract the mean from each individual value in the data set. Using the example above, subtracting the mean of 9 from each value would give you: 5 - 9 = -4, 7 - 9 = -2, 9 - 9 = 0, 11 - 9 = 2, and 13 - 9 = 4.

3. Find the absolute value of each of these differences, meaning that negative numbers are turned into positive. In the above example, the absolute values would be: |-4| = 4, |-2| = 2, |0| = 0, |2| = 2, and |4| = 4.

4. Sum up all the absolute differences. In the example, the sum would be: 4 + 2 + 0 + 2 + 4 = 12.

5. Divide the sum by the total number of values in the data set. Continuing with the example above, dividing 12 by 5 (the total number of values) gives you a deviation of 2.4.
