This concept of standard deviation can also be used for measuring statistical data which is also known as the expression for variability in the population, in this situation we can also use another name of standard deviation or it is mostly referred as the standard error of mean or the standard error of estimation in respect of the mean. There is not only one situation where we can opt for standard deviation there are various circumstances at which you can freely use standard deviation formula for lots of equations and questions. Let us come to explore about standard deviation in depth, if we talk about the value of standard deviation then by the formula itself we can say that it is directly proportional to the mean value or else we can say that if the mean value is low then the value for standard deviation will also be less or if the value of mean for data set is high then the value of standard deviation will also be high. Now let us come to the explanation of the formula of standard deviation. We all know that the symbol of the standard deviation is sigma. The only reason behind all this stuff is to make you understand the concept of calculating the standard deviation with fewer chances of mistake. Now, you might be thinking why we are discussing this topic or what is the need for learning standard calculations. Therefore, mostly all statisticians focus on the spreadsheets or either the computer programs for calculating a standard deviation. The only reason behind it is that standard deviation is quite a complex task and there is a high risk to create a mistake and apart from this making calculation by hand is a very slow procedure. Standard Deviation Formula for Ungrouped Data.As standard deviation is one of the hardest things so it can not be calculated by hands there is still no statistician who can calculate it on hands.
