# Unit: Sampling distributions

#### 0

### About this unit

If I take a sample, I don't always get the same results. However, sampling distributions—ways to show every possible result if you're taking a sample—help us to identify the different results we can get from repeated sampling, which helps us understand and use repeated samples.
