Hello everyone,

I performed a small research but could not identify a code for my need.

I want to create a sampling file in excel, that will have the population size in cell b2, and the required sample size in cell b5. (The required sample is to be up to 40.)

I want to create a macro that will read the population size and sample (from 1 to the population size) random numbers by the required times (cell b5) without duplication. The output of the random numbers is to be included in the area of f2:f41 (If required sample is less than 40, e.g. 5, then only fill cells f2:f6).

Could you please assist me?

Thank you very much for your input.

I've managed to create the following code, but I have yet to find a solution to not generate duplicates:

Code:
Sub Random_Sampling()
Dim LR As Integer
Dim i As Integer
Dim w As Integer
Worksheets("Random Sampling").Activate
Do Until i = Range("B5").Value
w = w + 1
Randomize
LR = Int((Range("B2").Value + 1) * Rnd + 1)
Cells(2 + i, 6).Value = LR
i = i + 1
Loop
End Sub
