How Do You Compute Population Standard Deviation Without Using A Computer Program?
The statistical term standard deviation refers to the dispersion of data about a mean (average) value. One can find the standard deviation of a sample of data or the standard deviation of an entire population. A sample is a subset of a population. The formulas for sample standard deviation and population standard deviation differ slightly, but the procedure used to obtain the result is the same. This article explains how to find the population standard deviation without using a computer program. The data I will use are the numbers 6, 4, 7, 8, and 0. Make a table with 6 rows and 4 columns. In row 1, put the column headings. Column 1 is Number. Column 2 is Mean of All Numbers in Set. Column 3 is Number – Mean of All Numbers in Set. Column 4 is (Number – Mean of All Numbers in Set) Squared. Now it’s time to start filling in the table. In Column 1, put the numbers 6, 4, 7, 8, 0. In Column 2, write the mean of 6, 4, 7, 8, and 0 in every blank spot. The mean is 5. It’s simply the average. In
