To obtain a representative sample

To increase variability

To ensure bias

To decrease sample size

The mean of the population

The variability of sample proportions

The exact population proportion

The mode of the sample

Sample proportions are always equal to population proportions

Sample proportions tend to cluster around the actual population proportion

Sample proportions increase variability

Sample proportions are not useful in statistics

It tends to be close

It is always lower

It is unrelated

It is always higher

It indicates a lack of variability

It shows the sample size is too small

It reflects the actual population proportion

It suggests the sample is not random

Makes variability unpredictable

Decreases variability

Increases variability
