Understanding Experimental Design

A small sample size

A large sample size

No sample size

A variable sample size

To introduce new variables

To remain constant and not exposed to the independent variable

To change the independent variable

To increase the sample size

The variable that is kept constant

The variable that is manipulated

The variable that is measured

The variable that is ignored

Having a large sample size

Having a small sample size

Having a consistent sample size

Having a variable sample size

To expose it to the independent variable

To ensure results are based on the independent variable

To change the dependent variable

To introduce extraneous variables
