3 kinds of sampling

Let's compare the performance of point estimates using simple, stratified, and cluster sampling. Before we do that, you'll have to set up the samples.

In these exercises, we'll use the RelationshipSatisfaction column of the attrition dataset, which categorizes the employee's relationship with the company. It's an ordered factor with four levels: Low, Medium, High, and Very_High.
