## How do you calculate a rolling average?

How do you calculate a rolling average? A rolling average continuously updates the average of a data set to include all the data in the set until that point. For example, the rolling average of return quantities at March 2012 would be calculated by adding the return quantities in January, February, and March, and then dividing that sum by three.

## Can you take the square root of i?

## How do you calculate the absolute difference?

How do you calculate the absolute difference? To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

## What happens if you multiply two functions?

What happens if you multiply two functions?
When you multiply two functions together, you’ll get a third function as the result, and that third function will be the product of the two original functions. For example, if you multiply f(x) and g(x), their product will be h(x)=fg(x), or h(x)=f(x)g(x). You can also evaluate the product at a particular point.Muh. 8, 1439 AH
