Statistical Measures and Excel Functions

This video tutorial explains how to calculate statistical measures such as mean, median, mode, range, standard deviation, and variance using Excel. It provides step-by-step instructions on using Excel functions like SUM, AVERAGE, MEDIAN, MODE, MAX, MIN, STDEV.S, and VAR.S to perform these calculations. The tutorial also covers the difference between sample and population standard deviation and variance, and how to use Excel to efficiently handle large datasets.

What is the difference between sample and population standard deviation?

• Sample uses median, population uses mean

• Sample uses mean, population uses median

• Sample uses n, population uses n-1

• Sample uses n-1, population uses n

How is the variance related to the standard deviation?

• Variance is the square of standard deviation

• Variance is double the standard deviation

• Variance is half of the standard deviation

• Variance is the square root of standard deviation
