Standard Deviation Equation, Formula & Examples from Chapter 13 / Lesson 4 217K The standard deviation of a data set is a measurement of how close, in aggregate, its values are to the mean. The baseline from
Generally, the standard deviation is denoted as sigma (σ). To find out the standard deviation, we have to follow some steps. First of all, we calculate the arithmetic mean. Then, we have to calculate the deviation for each observation using the formula,D = X - mean. What is the symbo...

I have two portfolios: one containing a risky asset and other containing a risk-free asset (T-Bills). How do I calculate the optimal weights between these two portfolios that would allow me to achieve a specific standard deviation on my complete portfolio?
We already have the mean for this data calculated (just the simpleAVERAGEfunction running in the background) Using these ages, let’s now find the standard deviation for this dataset through the STDEV function. Write the STDEV function as follows: ...
