## Select a Random Sample

Before we begin we will need a group of data to be used to select a random sample in Excel.

### Step 1

Make sure your group of data is displayed in a clean and tidy manner in the first sheet.

### Step 2

In this example, we want to select 20 emails to send a reward to by random. To do that we will use the RAND function and insert this formula =RAND().

### Step 3

We then sort the random numbers from smallest to largest value.
