In our case, we copy the formula to four more cells (C2:C6). Copy the above formula to as many cells as many random values you want to pick.Put the below formula in C2 to extract a random value from column A:.Enter the Rand formula in B2, and copy it down the column:.With the list of names in cells A2:A16, please follow these steps to extract a few random names: Generally, you'd use the RAND function to assign a random number to each cell, and then you pick a few cells by using an Index Rank formula. There are a few ways to select random data without duplicates in Excel.

How to randomly select in Excel without duplicates The next example shows how to do random selection in Excel without duplicates. It is especially the case when you are picking a relatively big sample from a relatively small list. If your sample is supposed to include several cells, the above formula may return several occurrences of the same value because the RANDBETWEEN function is not duplicate-free. This method works well for selecting one random cell from a list. For the column_num argument, we use 1 since we want to extract a value from the first column.

This number goes to the row_num argument of the INDEX function telling it which row to pick.

As the result, RANDBETWEEN returns a random number between 1 and the total count of rows in your dataset. For the upper value, you use either COUNTA or ROWS to get the total row count. For the lower value, you supply the number 1. More specifically, the RANDBETWEEN function generates a random integer between the two values you specify. In a nutshell, you use the INDEX function to extract a value from the list based on a random row number returned by RANDBETWEEN. Naturally, these formulas can not only pick random names, but also select random numbers, dates, or any other random cells. For the detailed instructions, please see How to replace formulas with values. To prevent this from happening, you can copy the extracted name and paste it as value to another cell ( Paste Special > Values). As the result, your random selection will also change. Please be aware that RANDBETWEEN is a volatile function, meaning it will recalculate with every change you make to the worksheet. That's it! Your random name picker for Excel is all set up and ready to serve: This can be done by using one of the following formulas: Supposing you have a list of names in cells A2:A10 and you want to randomly select one name from the list. These probably cannot be called simple intuitive formulas, but they do work. There's no built-in function to randomly pick cells in Excel, but you can use one of the functions to generate random numbers as a workaround. To get an impartial sample where everyone carries an equal opportunity of being chosen, do a random selection by using one of the methods described below. So, whom do your survey? Will that be 100 newest customers, or the first 100 customers listed alphabetically, or 100 people with the shortest names? None of these approaches fit your needs because they are innately biased. Obviously, it would be unwise to send out a questionnaire to each single person in your multi-thousand database. Why would you need one? Basically, to get a non-biased representation of the total population.ДЇor example, you want to conduct a little survey among your customers. Each element of a random sample is chosen entirely by chance and has an equal probability of being selected. In probability theory and statistics, a random sample is a subset of data selected from a larger data set, aka population.

Randomly select a number or percentage of cells, rows or columnsД«efore discussing sampling techniques, let's provide a bit of background information about random selection and when you might want to use it.

Pick a random number or text value from a list.
