This usually entails finding the mean, the standard deviation, and the standard error of the data. This article will show you how it's done. Steps Cheat Sheets Mean Cheat Sheet Standard Deviation Cheat Sheet Standard Error Cheat Sheet Method 1 The Data 1 Obtain a set of numbers you wish to analyze. This information is referred to as a sample. For example, a test was given to a class of 5 students, and the test results are 12, 55, 74, 79 and 90. Method 2 The Mean 1 Calculate the mean. Add up all the numbers and divide by the population size: Mean (μ) = ΣX/N, where Σ is the summation (addition) sign, xi is each individual number, and N is the population size. In the case above, the mean μ is simply (12+55+74+79+90)/5 = 62. Method 3 The Standard Deviation 1 Calculate the standard deviation. This represents the spread of the population. Standard deviation = σ = sq rt [(Σ((X-μ)^2))/(N)]. For the example given, the standard deviation is sqrt[((12-62)^2 + (55-62)^2 + (74-62)^2 + (79-62)^2 + (90-62)^2)/(5)] = 27.4. (Note that if this was the sample standard deviation, you would divide by n-1, the sample size minus 1.) Method 4 The Standard Error of the Mean 1 Calculate the standard error (of the mean). This represents how well the sample mean approximates the population mean. The larger the sample, the smaller the standard error, and the closer the sample mean approximates the population mean. Do this by dividing the standard deviation by the square root of N, the sample size. Standard error = σ/sqrt(n) So for the example above, if this were a sampling of 5 students from a class of 50 and the 50 students had a standard deviation of 17 (σ = 21), the standard error = 17/sqrt(5) = 7.6. Community Q&A Search Add New Question How do you find the mean given number of observations? wikiHow Contributor To find the mean, add all the numbers together and divide by how many numbers there are. e.g to find the mean of 1,7,8,4,2: 1+7+8+4+2 = 22/5 = 4.4.
