# What is Stdev function in Excel?

## What is Stdev function in Excel?

The standard deviation is a measure of how widely values are dispersed from the average value (the mean). Important: This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage.

## Should I use Stdev s or Stdev P?

STDEV. S assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the standard deviation using STDEV. P.

## How do you find the median example?

For example, 1, 2, 5, 6, 7, 8, 12, 15, 16, 17. The median is the number that comes in the middle of those middle two numbers (7 and 8), so that number would be 7.5 in this case. (To do this mathematically, add the two numbers together and divide by 2).

## How do you find the median of a Class 9?

For example, the median of 3, 3, 5, 9, 11 is 5. If there is an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values: so the median of 3, 5, 7, 9 is (5+7)/2 = 6.
