Step-by-step explanation:

The standard deviation is the measure of dispersion or the spread of the data about the mean value. It helps us to compare the sets of data that have the same mean but a different range. The sample standard deviation formula is: s=√1n−1∑ni=1(xi−¯x)2s=1n−1∑i=1n(xi−x¯)2, where ¯xx¯ is the sample mean and xixi gives the data observations and n denotes the sample size.
