Standard Deviation of the Mean (SDOM): The calculator returns the standard deviation of the mean(σM).
The Math / Science
The standard deviation of the mean (SDOM) is sometimes also known as the standard error of the mean (SEM). This quantity is useful in that it helps quantify the uncertainty in the estimate of the mean.
Observational Stats: This function accepts a table of numbers separated by commas and calculates observational statistics for any of the columns. This includes count, min, max, sum, sum of squares (Σx²), square of the sum (Σx)², mean, median, mode, range, mid point, rand, sort up, sort down, rand, population variance, population standard deviation, the sample/experimental variance, sample/experimental standard deviation.
Frequency Distribution: This function lets you enter a string of numbers separated by commas, a low and high range and a number of bins. It then computes how many of the observations are in each of the bins between the high and low values designated.
