The Standard Deviation is a measure that describes how spread out values in a data set are. In Python, Standard Deviation can be calculated in many ways - the easiest of which is using either Statistics' or Numpy's standard deviant (std) function In almost all the case, we use the STDEV.S formula to calculate standard deviation in excel. This is used when we want to use only the numerical values and ignore the text values. If at all you want to use text values in the range use STDEVA And in general, for many uses the standard deviation ends up luring one into a false feeling of understanding. For instance, if the distribution is anything but normal (or a good approximation thereof), relying on the standard deviation will give you a bad idea of the shape of the tails, when it is exactly those tails that you probably most care about in statistical testing. $\endgroup.
Standard Deviation of a dataset tells you how much the data deviates from the mean. For example, suppose you have a class of 50 students and their score in the Math exam. Now, if the mean score is 70 and the standard deviation is 10, it means that most of the student's score is in +/- 10 range from the mean (i.e., most students has marks between 60 and 80) This Excel Tutorial demonstrates how to use the Excel STDEV Function in Excel to calculate the standard deviation, with formula examples.
