The Excel STANDARDIZE Function. Basic Description. The Excel Standardize function returns a normalized value of a distribution that is characterized by a supplied mean and standard deviation. The syntax of the function is: STANDARDIZE( x, mean, standard_dev ) Where the function arguments are:
Excel has some very useful functions for finding areas under the normal distribution. NORMSDIST(z) Z is the value for which you want the distribution. Returns the standard normal cumulative distribution function. The distribution has a mean of 0 (zero) and a standard deviation of one.Use this function in place of a table of standard normal curve areas. 1  a) Pick a cell and enter a z score into it (for example 2), dont forget to add a label so youll know what you put in this cell.ry other values of z in order to get a better feeling for the use of this function, for example 0,1,5,-1,-3) NORMSINV (probability). Excel has some very useful functions for finding areas under the normal distribution. NORMSDIST (z). Z is the value for which you want the distribution.
