![]() While I want a randomized result, I know that the test scores are not going to be uniformly distributed between 0 and 100. The lowest possible score is 0 and the highest possible score is 100. For example, let’s say that I wanted to simulate the test scores for a group of students on an exam and I know from past history that the average score is a 80. While Excel’s random number generating formula will help you some situations, there are many analysis and simulation cases where it simply won’t be realistic. If you need to create a purely random set of numbers, with no specific constraints or parameters, you can just use the RAND function in Excel to generate those numbers for you. 60-day money back guarantee.Whether you’re building a model or trying to simulate a scenario within your analysis, at some point in your Excel career, you’re going to need to use a randomized set of data.

If you want to insert random and no duplicate integer numbers, dates, times or strings, even custom lists into a range of cells, the forumula maybe hard to remember. Tip: D3:D16 is the range of the last random number series.Įasily Insert Random Data without duplicates in a range of cells In cell D17, type =AVERAGR(D3:D16) and press Enter key, then in cell D18, type =STDEV.P(D3:D16) (or =STDEVP(D3:D16) in Excel 2007) and press Enter key. ![]() You can check the mean and standard deviation of the final random number series.ĥ. Tip: B1 indicates the mean you need, B2 indicates the standard deviation you need, B3 indicates the first cell of your first random numbers, D1 is the mean of first random numbers, D2 is the standard deviation of first random numbers. In cell D3, type this formula =$B$1+(B3-$D$1)*$B$2/$D$2, and drag the fill hand to the range you need. Now you can generate the real random numbers you need. Tip: B3: B16 is the range you randomize numbers in step 2.Ĥ. Tip: In Excel 2007, you need to type the formula =STDEVP(B3:B16) to calculate the standard deviation of the first random numbers. In D1, calculate the mean, type =AVERAGE(B3:B16), press Enter key and in D2, calculate the standard deviation, type =STDEV.P(B3:B16) and press Enter key. Then in cell D1 and D2, you need to calculate the mean and standard deviation of the random number you has inserted in step 2. Tip: In the formula =NORMINV(RAND(),$B$1,$B$2), $B$1 indicates the mean, $B$2 indicates the standard deviation.ģ. Then in cell B3, type this formula =NORMINV(RAND(),$B$1,$B$2), and drag the fill handle to the range you need. Firstly, you need to type your needed mean and standard deviation into two empty cells, here, I select A1 and A2. To solve this problem, you need to do as below steps:ġ. Generate random number by given mean and standard deviation In some certain cases, you may want to generate a series of random numbers based on given specific mean and standard deviation, how could you quickly solve this problem? Now this tutorial will introduce a way for you to handle with it in Excel. Generate random number by given certain mean and standard deviation in Excel
