A measure of how spread out a set of numbers is from their average value.
Experimente com IAStandard deviation quantifies the amount of variation or dispersion in a dataset. A low standard deviation indicates that values are close to the mean, while a high standard deviation indicates that values are spread over a wider range. It is calculated as the square root of the variance.
=STDEV.P(range) or =STDEV.S(range)If a class test average is 80, a low standard deviation means most students scored near 80, while a high standard deviation means scores varied widely from very low to very high.
STDEV.P calculates standard deviation for an entire population, while STDEV.S calculates it based on a sample of the population.
