Question
The variance or standard deviation tell about the population tell you that how various sub-population are spread out from the mainpopulation. The mean can tell you only average or mean of various sub-population. The variance or standard deviation tell you deviation of data points from the mean.
The mean and median are two statistical approaches that are use when viewing a histogram.

What do the variance, S.E., or standard deviation estimates tell you about your population that the mean does not tell you? Why is it important to report some measure of variation, along with the sample size, whenever you report a calculated mean?

Descriptive statistics like mean, median, range, and standard deviation can be used to summarize data. But the value isn't in knowing how to calculate these numbers, it's in knowing what they mean—or even which ones to consider. This discussion explores that by asking you to take a strictly hypothetical look at a serious circumstance. An article you might want to consider in this context is Stephan Jay Gould’s The Median Isn’t the Message. 1. If you were diagnosed with a...
