For example: 409.0 304.0 -323.2 496.9 -151.5 841.7 551.3 822.1 292.2 -720.0 984.7 941.1 952.4The empirical rule calculator (also a 68 95 99 rule calculator) is a tool for finding the ranges that are 1 standard deviation, 2 standard deviations, and 3 standard deviations from the mean, in which you'll find 68, 95, and 99.7% of the normally distributed data respectively. Standard deviation calculator For standard deviation calculation, please enter numerical data separated with comma (or space, tab, semicolon, or newline). σ = √ (12.96 + 2.56 + 0.36 + 5.76 + 11.56)/5 = 2.577 Sample Standard Deviation In many cases, it is not possible to sample every member within a population, requiring that the above equation be modified so that the standard deviation can be measured through a random sample of the population being studied. You can either enter the numbers in the data set one at a time, or you can copy and paste an existing data set (if separated by spaces, commas, line returns, or any combination thereof), or you can enter a number and its frequency (12x4, 8圆, 9x4). Scores Population or Sample Population Sample Remember, if your data represents a whole population, then you need to select Population above.This calculator will calculate the variance and standard deviation for either a population or a sample data set. Just enter your data into the textbox below, either one score per line or as a comma delimited list, and then press 'Calculate'. 20% 125 = 25 where 25 is 20% of 125.This simple tool will calculate the standard deviation of a set of data. Enter the percentage amount, click the % button, then enter the number you want the percentage of, and then click equals. Percent button is used to find the percentage of a number. Enter a number, then click square root button. Square root button is used to calculate the square root of a number.
