Standard_Dev: Standard Deviation is a function to find the deviation of the data.

Mean: Mean is whereas average of the data.

X: X is the specified value for which we want to calculate normal distribution.It has three basic factors to calculate the normal distribution in excel Normal Distribution In Excel NORMDIST or normal distribution is an inbuilt statistical function of excel that calculates the normal distribution of a data set with mean and standard deviation provided. Seems so complex, right? But excel has made it easier for us to calculate normal distribution as it has a built-in function in excel of the normal distribution. In mathematics, the equation for a probability distribution is as follows: read more is used to calculate real-time occurrences of any phenomenon. A continuous probability distribution Probability Distribution Probability distribution could be defined as the table or equations showing respective probabilities of different possible outcomes of a defined event or scenario. BY definition, a normal distribution means how evenly the data is distributed. The basic idea of what is a normal distribution is explained in the overview above. There are two types of probability distributions, Discreet and continuous.

A probability distribution is a function that is used to calculate the occurrence of a variable. We all know what probability is it is a technique to calculate the occurrence of a phenomenon or a variable. Excel Normal Distribution Graph (Bell Curve)Ī normal distribution Graph is a continuous probability function. Normal distribution graph in excel is used to represent the normal distribution phenomenon of a given data, this graph is made after calculating the mean and standard deviation for the data and then calculating the normal deviation over it, from excel 2013 versions it has been easy to plot the normal distribution graph as it has inbuilt function to calculate the normal distribution and standard deviation, the graph is very similar to the bell curve.
