Here are the steps you need to follow to calculate normal distribution in Excel. Step 1: Enter Your Dataset into an Excel Spreadsheet To get started, enter your data into an Excel spreadsheet in an organized manner to facilitate the calculation of Excel's normal distribution. Excel is designed...
So how do we calculate the probability below a negative z-value (as illustrated below)?We start by remembering that the standard normal distribution has a total area (probability) equal to 1 and it is also symmetrical about the mean. Thus, we can do the following to calculate negative z-...
While most people are familiar with a normal distribution, they may not be as familiar with a log-normal distribution. A normal distribution can be converted to a log-normal distribution using logarithmic mathematics. That is primarily the basis as log-normal distributions can only come from a n...

You need to calculate the required minimum distribution for each retirement account individually. You can make the total withdrawal from one account, however, or a combination of accounts. Your RMD is determined by dividing the balance in any given account at the end of the prior calendar year ...
Be sure to usesignificant figureswhen rounding your final answer. A Worked Example Suppose you're given the data set 1, 2, 2, 4, 6. Work through each of the steps to find the standard deviation. Calculate the mean of your data set. The mean of the data is (1+2+2+4+6)/5 = ...
How Do You Calculate the Median? The median is the middle value in a set of data. First, organize and order the data from smallest to largest. Divide the number of observations by two to find the midpoint value. Round the number up if there's an odd number of observations and the va...

Calculate the standard deviation of the distribution. Subtract the average of the sample means from each value in the set. Square the result. For example, (6 – 7)^2 = 1 and (8 – 6)^2 = 4. These values are called squared deviations. In the example, the set of squared deviations ...
