If the cumulative value is “true,” the NORMDIST function returns the cumulative normal distribution function (CDF).The NORMDIST function accepts four arguments–X value, mean, standard deviation, and cumulative value.The NORMDIST function calculates the normal distribution of a data set for which the mean and standard deviation are given.However, STDEV.P and STDEV.S are only available in Excel 2010 and subsequent versions. STDEV is available in Excel 2007 and the previous versions. In Excel, the STDEV and STDEV.S calculate sample standard deviation while STDEVP and STDEV.P calculate population standard deviation.

The average formula is =AVERAGE( read more and STDEV.S function STDEV.S Function The standard deviation shows the variability of the data values from the mean (average). This formula is categorized as a Statistical Function. The NORM.DIST function requires the mean and standard deviation which can be calculated by average function Average Function The AVERAGE function in Excel gives the arithmetic mean of the supplied set of numeric values.It gets its name from the shape of the graph which resembles to a bell.

The normal PDF is a bell-shaped curve Bell-shaped Curve Bell Curve graph portrays a normal distribution which is a type of continuous probability.

read more” if any of the supplied arguments is a non-numeric value. Sometimes, it is difficult to identify the kind of mistake behind this error.

The NORMDIST function returns “ #VALUE! error #VALUE! Error #VALUE! Error in Excel represents that the reference cell the user has either entered an incorrect formula or used a wrong data type (mostly numerical data).

The NORMDIST function returns “#NUM! error” if the standard deviation supplied is less than or equal to zero.

The NORM.DIST function accepts only numerical values.

The Characteristics of the Normal Distribution Function

How to Use NORMDIST in Excel? (With Examples) However, it may not be available in future versions of Excel. Note: The NORMDIST function exists in the recent versions of Excel to support compatibility with the previous versions.

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.
