Commonplace deviation (STDEV) is a measure of how unfold out a set of knowledge is. It’s calculated by discovering the sq. root of the variance, which is the typical of the squared variations between every information level and the imply. STDEV is a helpful statistic for understanding the variability of a knowledge set and for evaluating completely different information units.
In a TI-84 calculator, you will discover the STDEV of a knowledge set through the use of the next steps:
