Simple random selection involves a selection where all the elements in the dataset have the same chance of being selected.

The selected names are:

<em>Engler, Motola, Redmond and Zenkel</em>

We have:

n =32 --- All names

r = 4 ---- Sample to select

There are several ways to select a sample of 4 using a simple random sample. Some ways are:

  • <em>Select any 4</em>
  • <em>List all names in even position and select the first 4</em>
  • <em>List all names in position divide by 4 and select any 4 that is divided by 8</em>
  • <em>List all names in odd position and select the first 4 that can be divided by 3</em>
  • <em>Etc</em>

<em />

Going by the third method, the selected positions are:

4, 8, 12, 16, 20, 24, 28 and 32

Select 4 positions that can be divided by 8

8, 16, 24 and 32

So, the selected names are:

<em>Engler, Motola, Redmond and Zenkel</em>
