Use the Sampling Analysis tool in Excel to easily select random numbers.

This week’s tip is especially handy when running competitions for your business, so please share it with your promotions and marketing teams. The Sampling Analysis Tool is great for when you need to randomly select a number from a given range of values. An example of this is the following; say your marketing team is running a lucky draw competition and needs your help in selecting a winner by random, you can use the Sampling Analysis tool to ensure that this winner is selected without favour.
