Standard deviation (STDEV)
Calculates the STDEV (
) of the data-set. The STDEV is an indication of the variation of the data. A small STDEV means a small variation and the data points are close to the Mean
The bigger the STDEV the bigger the variation in the data-set.
95% confidence interval for STDEV
To get the Confidence interval click on the graph of the data-set and it will be visible in the graph pop-up.
n = n
s = STDEV
The STDEV of samples in data-set A is 1.1136, this is visible in row STDEV
of the result array.
