Calculating the standard deviation in Excel is just one of the almost infinite functionalities offered by Microsoft spreadsheets . And, according to the latest data provided by Bill Gates' company, up to 15% of the world's population uses this tool for all types of tasks . Taking this information into account, having advanced knowledge in Excel is key to increasing productivity and continuing to grow as a professional. Do you want to know more about this advanced feature? We tell you how you can calculate the standard deviation in Excel step by step. CTA Post What is the typical or standard deviation? The standard deviation or typical deviation is a statistical tool that allows calculating the degree of deviation of a set of data , taking their average as a reference. That is, thanks to it, it is possible to easily measure the degree of dispersion of the data and the separation that exists with respect to the average. The standard deviation is represented by an integer , which is always greater than or equal to zero.
This number indicates how dispersed a data set is from the mean . Consequently, the higher the standard deviation, the more dispersed and distant the data will be from each other, and conversely: the lower this number, the more homogeneous the set of data analyzed will be. What is the standard deviation for? Example The standard deviation is a function that is applied in probability and statistics studies , having its main use in the study of grouped data. Likewise, this tool Europe Mobile Number List is used in a multitude of areas and fields, although, in general, it is useful in the study of demographic data. It allows measuring the reliability of statistical conclusions , minimizing the margin of error and reducing uncertainty , since it is possible to check whether the measurements agree with the theoretical prediction. This is very useful in fields such as finance, meteorology or experiments, as well as in industrial and hypothesis testing. To understand it better, let's look at an example of standard deviation. Imagine that you want to find out what the average age is of different groups of friends.
Calculate the mean, you will only know the average age, but if you apply the standard deviation, you will be able to know how dispersed the age of these groups of friends is. Do you still not understand what it is for? Let's say that the average of all the groups analyzed is 25 years old . However, one of them has a standard deviation of 1 and another of 5. This means that, in the first, they all have a very similar age , between approximately 24 and 26 years old, while, in the second group , like the standard deviation is greater, the ages are much more diverse , with people between 20 and 30 years old. standard-deviation-in-excel How to calculate the standard deviation in Excel step by step Calculating the standard deviation in Excel is extremely simple thanks to the DEVEST.M() function. This allows us to calculate the standard deviation of a set of data that we have entered into Excel. We explain how to do it step by step: Open Excel and create a new spreadsheet . Enter your data set in a column. These can be, for example, the age of a group of people.
