Excel’s NORM.DIST function can be used to compute
the cumulative probability of a given value in a normal distribution
the cumulative probability of a given value in a normal distribution. It takes four arguments: x, mean, standard deviation, and cumulative.
The “x” argument represents the value for which you want to compute the cumulative probability. This value must be a numerical input.
The “mean” argument is the average or mean value of the normal distribution. It represents the central tendency of the distribution and is also a numerical input.
The “standard deviation” argument shows the spread or variability of the normal distribution. It represents how much the values deviate from the mean. It is also a numerical input.
The “cumulative” argument is a logical value that determines whether you want to calculate the cumulative distribution function (CDF) or the probability density function (PDF). If cumulative is set to TRUE, NORM.DIST calculates the cumulative distribution function, which represents the probability that a value will be less than or equal to the given value. If cumulative is set to FALSE, NORM.DIST calculates the probability density function, which represents the probability density at a specific value.
By using the NORM.DIST function in Excel, you can easily determine the probability of a certain value occurring in a normal distribution based on the mean and standard deviation.
