Now, instead of using TRUE as a value for the cumulative argument, use FALSE. You can follow steps 2 to 4 from the previous example. Input all the values for x, mean & standard_dev same as in the previous example. Start typing the formula for normal distribution.

We will see step by step how to achieve this result as well. Suppose, in the example above, you want to find out the chances/probability that you reach the office at exactly 48 minutes, then? Example #2 вЂ“ Finding out the Value for Normal Probability Density Function

Consequently, there are 21% chances that you will be reaching the office in more than 48 minutes. You can see that there are almost 79% chances that you will reach the office within 48 minutes. Press Enter key and see the output for this formula. We have set all the arguments that are mandatory to determine the cumulative probability that you reach the office within 48 minutes. ItвЂ™s there in cell B3.ДЄt last, mention a logical argument as TRUE as we want to find out the chances/probability that you reach the office within 48 minutes (or before 48 minutes). Mention the next argument, which is a standard deviation in terms of minutes to reach to office. The second argument will be the mean time it takes to reach to office, which is already set under cell B2. the value of x, which is already set in cell B1. Mention the first argument, which is the value you want to find the normal probability for, i.e. The best thing about excel is that it gives you all the arguments associated with the function as soon as you type the keyword. Start typing the formula for normal distribution in cell B4. In cell B4, you will be calculating the normal probabilities.In cell B3, you have the value for standard deviation in terms of time to reach to office.In cell B2, we have the average time taken to reach to office.In cell B1, there is a time we want to find the normal probabilities for.See the screenshot below for better visualization of this problem: With the standard deviation of 10 minutes (10 minutes late or 10 minutes early) and the assumption that the time it takes you to reach the office is normally distributed with the mean mentioned above, what are the chances/probability that you reach to office in less than 48 minutes?

We are going to use NORM.DIST in order to find pdf and CDF for normal distribution. Maybe in the latest release of Microsoft Excel (Excel 2019), you may not see this version of the formula. After 2010 onwards versions of excel, NORMDIST is replaced by NORM.DIST. However, if you will read the instructions properly, it is there just to use an excel file with version 2007 or earlier. In Excel, you can find out NORMDIST as well, which has the same functionality. If set FALSE, it gives value for Normal Probability Density Formula.

If set TRUE, it gives value for Cumulative Normal Distribution Formula. Standard_dev вЂ“ A required argument that is nothing but the standard deviation (square root of variance) of normal distribution.Д¬umulative вЂ“ Is a logical value that specifies the type of normal distribution to be calculated.
