Question

Calculate population standard deviation from sample standard deviation

Answer 1

Explanation:

Standard deviation is a calculation of the dispersion or variation in a set of numbers. If the standard deviation is a small number, it means the data points are close to their average value.

There are two types of standard deviation calculations. Population standard deviation looks at the square root of the variance of the set of numbers. It's used to determine a confidence interval for drawing conclusions (such as accepting or rejecting a hypothesis). A slightly more complex calculation is called sample standard deviation. This is a simple example of how to calculate variance and population standard deviation. First, let's review how to calculate the population standard deviation.
