This same formula can be applied to find the standard deviation of returns. In this case, the variables will be: {eq}\sigma {/eq} is the standard deviation of returns. {eq}x_i {/eq} is the historical returns of this stock per month. {eq}\mu {/eq} is the average return of this...
Return = (End_price + Dist_per_share - Start_price) / Start_priceIf the comparison period is 5 years, there are 60 monthly returns. The standard deviation of returns for the calculation object uses the formula:The object's standard deviation is a combination of the value weight and return...

Standard deviation is automatically computed by the statistical analysis software you employ. However, it can also be manually calculated to comprehend the underlying formula better. To manually calculate Standard Deviation, you must follow six primary steps. These steps are described below: Step 1:...
The formula for Standard Deviation is:Say what? Please explain!OK. Let us explain it step by step.Say we have a bunch of numbers like 9, 2, 5, 4, 12, 7, 8, 11.To calculate the standard deviation of those numbers:1. Work out the Mean (the simple average of the numbers) 2. ...
We can find the standard deviation of a set of data by using the following formula: Where: Ri– the return observed in one period (one observation in the data set) Ravg– thearithmetic meanof the returns observed n– the number of observations in the dataset ...
The standard deviation of a data set is a measurement of how close, in aggregate, its values are to the mean. The baseline from which this distance...
The standard deviation formula that you will use to find the standard deviation (SD) is shown below.x represents a set of numbers. For example, x could be {5, 6, 14, 1, 6, 10}. The mean is the average of the set of numbers....
The standard deviation measure how individual values are spread around the mean. In our question, the standard deviation is measuring the extent to which individual returns are spread around the mean return. The formula to adopt in...
Like STDEV, the STDEV.S function calculates the sample standard deviation of a set of values based on the classic sample standard deviation formula discussed in the previous section. Excel STDEVA function STDEVA(value1, [value2], …)is another function to calculate standard deviation of a sample...
