To find the variance, we first need to calculate the mean (average) of the data set. Add all the values together and then divide by the number of values.
- Calculate the mean:
- Next, subtract the mean from each number, square the result, and then find the average of those squared differences.
Calculating those steps gives us:
After performing these calculations, you will find that the variance is approximately 809.72.
