How To Calculate 2 Standard Deviations In Excel

Jump to

    Calculating standard deviations is a fundamental statistical task, commonly performed during data analysis to understand variability. Excel users frequently utilize the STDEV.S or STDEV.P functions to find this value.

    However, executing these calculations in Excel can involve multiple steps that may be streamlined in alternative tools.

    Later in this guide, we'll explore Sourcetable, a platform designed to simplify such processes, making it easier than traditional methods in Excel.

    Calculate 2 Standard Deviations in Excel

    Understanding the Empirical Rule

    Under the Empirical Rule, about 95% of data in a normal distribution lies within two standard deviations from the mean.

    Calculating Two Standard Deviations

    Use the formula =2*STDEV.S(range) to calculate two standard deviations. Excel's STDEV.S function computes the standard deviation for a sample set.

    Using the Formula

    Apply =2*STDEV.S(A2:A14) for two standard deviations over a specific range, replacing A2:A14 with your data range.

    Example Dataset Calculation

    In an example dataset with the mean of 77.07, the calculation yields two standard deviations at 16.03, establishing benchmarks at 61.0465 below and 93.1073 above the mean.

    Standard Deviation vs. Standard Error

    Remember, standard deviation differs from standard error, which estimates the sample mean's deviation from the population mean.
