What is how to find the mean of a data set?

To find the mean of a data set, follow these steps:

1. Sum all the values: Add up all the numbers in the data set. For instance, if your data set is 2, 4, 6, 8, 10, you would add 2 + 4 + 6 + 8 + 10.

2. Count the number of values: Determine how many numbers are in the data set. In the example above (2, 4, 6, 8, 10), there are 5 values.

3. Divide the sum by the count: Divide the sum calculated in step 1 by the number of values calculated in step 2. Using the example, divide the sum (30) by the count (5): 30 / 5 = 6.

The result is the mean. In the example above, the mean is 6.

The mean is also sometimes referred to as the average. Remember to include all values when summing, and to accurately count the total number of values.
