To calculate the average and standard deviation: 1. Calculating the Average in Excel 1.1. Computing the Average Manually Use the formula: =SUM(D5:D12)/COUNT(D5:D12) The SUM function returns the total scores and the COUNT function counts the number of scores. Total scores are divided by...
Step 3: Take the difference to determine your equity Once you have your home’s value and your mortgage balance, you’re almost finished. From here, all you need to figure out how to calculate equity is some simple subtraction. Your home equity equals the current value of your home minus...
Knowing the relative fraction of each isotope of a particular element that occurs in nature allows you to calculate the atomic mass of that element, which, because it is an average, is not the mass of any one atom but a number that is between the heaviest and lightest isotopes pres...
Calculate thesimple moving average (SMA)for the chosen number of time periods. (The EMA uses an SMA as the previous period's EMA to start its calculations.) To calculate a 12-period EMA, this would simply be the sum of the last 12 time periods, divided by 12. Weig...
How to calculate variance Step 1:Determine the sample mean ( Add up all the values in your dataset and divide by the total number of values to find the average value) Step 2:Subtract the mean from each individual value in your dataset. ...

Use your midterm grade, expressed in a percentage, to find a midterm average for all your homework and tests. An equation for this particular calculation could look like this: MA = (0.5HWa + 0.25ME) / (0.75). Take note that the "0.25" means that the midterm exam (ME) was worth 25...
Copy this equation into each row for all time periods. Next, calculate the average of the excess return values in a separate cell. In another open cell, use the =STDEV function to find thestandard deviationof excess return. Finally, calculate the Sharpe ratio by dividing the average by the...
Suppose someone drives a car from one city to another and you are asked to calculate the average speed, in miles per hour, that the car traveled. The information you are given can influence how you approach the problem. As long as you can determine the t
Step 1: Calculate the average The first thing you need to do to calculate the standard deviation of the sample is to work out the average value. To do this you simply add up all the values in your sample, and divide the answer by the number of values in the sample. ...
