how to calculate Mean Standard Deviation And Standard Error in Excel | Step by Step Guide

There are several kinds of mean in mathematics, especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value of a given data set.
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
The standard error of the mean, or simply standard error, indicates how different the population mean is likely to be from a sample mean.
