If the cumulative value is “false,” the function returns the normal probability density function (PDF). If the cumulative value is “true,” the function returns the cumulative normal distribution function (CDF). Cumulative: This is a logical value that determines the type of distribution to be used.Standard Deviation: This is the standard deviation Standard Deviation Standard deviation (SD) is a popular statistical tool represented by the Greek letter 'σ' to measure the variation or dispersion of a set of data values relative to its mean (average), thus interpreting the data's reliability.Mean: This is the average value of the distribution, i.e., the mean value.X: This is the value for which we calculate the normal distribution.The arguments of the NORM.DIST function are listed as follows: Source: NORMDIST in Excel (Normal Distribution) ()

This distribution has two key parameters: the mean (µ) and the standard deviation (σ) which plays a key role in assets return calculation and in risk management strategy. The syntax of the normal distribution Normal Distribution Normal Distribution is a bell-shaped frequency distribution curve which helps describe all the possible values a random variable can take within a given range with most of the distribution area is in the middle and few are in the tails, at the extremes. The Excel 2010 replaced the NORMDIST function with NORM.DIST function. NORMDIST function accepts four arguments–X value, mean, standard deviation, and cumulative value. NORMDIST or normal distribution is an inbuilt statistical function of Excel that calculates the normal distribution of a data set for which the mean and standard deviation are given.
