This free standard deviation calculator computes the standard deviation, variance, mean, sum, and error margin of a given data set.
Use this Mean and Standard Deviation Calculator to get step-by-step calculation of the sample mean, variance and standard deviation
Sep 19, 2023 · A low standard deviation indicates that data points are generally close to the mean or the average value. A high standard deviation indicates greater variability in data points, or higher dispersion from the mean. This standard deviation calculator uses your data set and shows the work required for the calculations.

Home > This page. Statistics Calculator. Compute values for common data set attributes (mean, median, mode, standard deviation, variance, range, interquartile range, skewness, etc.). For help in using the calculator, read the Frequently-Asked Questions or review the Sample Problem.
Quick and easy to use stdev calculator, that also outputs variance, standard error of the mean (SEM), mean, range, and count. Learn what standard deviation is in statistics and probability theory, what is the formula for standard deviation, and practical examples.
The standard deviation calculator calculates the standard deviation of a set of numbers. In addition, it provides additional information about the numbers, including the mean and the variance. The calculator also calculates the confidence interval of the dataset for different confidence levels and provides the frequency distribution table.
Use the standard deviation calculator to compute both sample standard deviation and population standard deviation, complete with a step-by-step solution, and then present the results in APA format.
6 days ago · Standard deviation is the square root of variance, representing data dispersion in original units. What is the significance of variance in statistics? Variance helps determine data consistency; low variance suggests similar values, while high variance indicates wider spread.
