After more than 300 years, the origin of the Gauss Bell, an important mathematical and statistical tool , continues to be the subject of controversy among scholars of these fields. Some credit its invention to the French statistician Abraham de Moivre, while others see traces of its first appearances in documents by Galileo Galilei. However, most attribute the invention of the Gauss Bell to the German mathematician, physicist and astronomer Carl Friedrich Gauss , since, in addition to giving it its name, he was the one who laid the foundations for the theory of the normal distribution . Do you want to delve a little deeper into this concept? Next, we show you how to make a Gaussian Bell in Excel , what data you need and how you should interpret the results. CTA Post What is a Gauss bell? A Gaussian Bell is a graphical representation that shows the distribution of data around a central value . This tool is used to represent the dispersion of data and its trend, in order to detect patterns or behaviors in different situations.
The Gaussian Bell is a normal, smooth curve that is drawn in the shape of a bell on a horizontal axis ; hence its name. In this case, said curve represents the distribution of data around the mean, that is, the point at which the majority of frequencies with which the values are found are concentrated. Furthermore, it should be noted that it is a symmetric function , so both sides of the bell will always be equal with respect to the midpoint. In this way, with the Europe Mobile Number List Gauss Bell it is possible to establish a series of parameters that help predict and rationalize what apparently are random results , obtaining a clearer and more visual version of the normal distribution of a set of numbers. What data do you need to draw a Gaussian Bell in Excel? To draw a Gaussian Bell in Excel, the first thing you need is to have a set of data to work with . These can be a demographic's height, salary, age, college qualifications, etc. In short, you must have a set of statistical data from which you want to draw conclusions.
Once you have these data, you must calculate their average to determine the central value around which the Gauss Bell will be drawn. In this sense, to obtain the average, you must add the values of all the data and divide the result by the total amount of data available. The resulting number will be the highest value on the graph. On the other hand, it is also necessary to calculate the standard deviation and the normal distribution. The standard deviation allows us to measure the closeness of each of the values to the mean. In this way, the further away they are, the larger the standard deviation will be, that is, the further away it will be from the average. As for the normal distribution, it is used to know how likely it is that the values are close to the mean. To calculate it, all the previous values are needed, as well as the range of data that you want to cover with the Gaussian Bell, which must coincide with the data set you are working with. gauss-bell-excel How to draw a Gaussian Bell in Excel? Next, we explain step by step how you can calculate all the above values and how you can draw a Gauss Bell in Excel.
