Standard deviation with only mean
WebbDescribes the uncertainty, due to sampling error, in the mean of the data. It is calculated by dividing the standard deviation by the square root of the sample size ( ), and so it gets smaller as the sample size gets bigger. In other words, with a very large N, the sample mean approaches the population mean. Webb14 apr. 2014 · In the first one, the standard deviation (which I simulated) is 3 points, which means that about two thirds of students scored between 7 and 13 (plus or minus 3 points from the average), and virtually all of them (95 percent) scored between 4 and 16 …
