Question
What is the standard deviation of the following data set? Feel free to use the STDEV.S function in Excel!x = { 2, 5, 6, 7, 10 }Round your answer to the nearest hundredths place (X.XX format).
Solution
To calculate the standard deviation of the data set {2, 5, 6, 7, 10}, you can follow these steps:
-
Calculate the mean (average) of the data set. Add all the numbers together and then divide by the count of numbers. (2+5+6+7+10) / 5 = 6
-
Subtract the mean from each number in the data set and then square the result. This gives you
