What does the independent variable represent in the study?

• The weather conditions

• The color of the car

• The speed of the car

• The mood of the driver

Why do we isolate the independent variable?

• To make the study cheaper

• Because it's easier to measure

• To ensure it's the only variable that changes

• To make the study more complex

Why must other variables remain constant?

• To ensure accurate measurement of the dependent variable

• To shorten the duration of the study

• To make the study more interesting

• To reduce the cost of the study
