Explanation:

Fair Test tries to keep all other variables constant.

In order to ensure that only the independent variable is affecting the dependent variable (the outcome that will be measured), all the other factors (variables) acting upon the test situation must be kept constant (the controlled variables).

Answer 2

A Fair Test tries to keep all other variables constant.

Explanation:

• It is important for an experiment to be a fair test.
• You conduct a fair test by making sure that you change one factor at a time while keeping all other conditions the same.
• For example let's imagine that we want to measure which is the fastest toy car to coast down a sloping ramp.
• In order to ensure that only the independent variable is affecting the dependent variable (the outcome that will be measured) all the other factors (variables) acting upon the test situation must be kept constant (the controlled variables).
• The controlled variable is a process parameter being controlled.
