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.įor 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. Before discussing sampling techniques, let's provide a bit of background information about random selection and when you might want to use it.
