In the recipes mentioned so far, we have shown the importance of monitoring and analyzing frequency to determine the likelihood that an event will occur. Standard deviation will now allow for an analysis of the frequency in a different manner, or more specifically, through variance. With standard deviation, we will be able to determine the basic top and bottom thresholds of data, and plot general movement within that threshold to determine the variance within the data range. This variance will allow the calculation of risk within investments.
As a financial manager, you must determine the risk associated with investing capital in order to gain a return. In this particular instance, you will invest in stock. In order to minimize loss of investment capital, you must determine the risk associated between investing between two different stocks, Stock A, and Stock B.
In this recipe, we will utilize standard deviation to determine which stock, either...
