Interpretation : The difference between the independent variable and dependent variable is to be defined.
Concept Introduction : The experiment when constructed usually deals with variables or factors that change.
Answer to Problem 47A
An independent variable keeps changing during an experiment whereas the dependent variable changes according to the independent variable.
Explanation of Solution
The independent variable is the one you modify during an experiment.
A dependent variable is measured during an experiment. It is also called a manipulated variable.
You can relate any change in the dependent variable to any other factors that could alter and affect the experiment. It is also called a responding variable.
An independent variable keeps changing during an experiment whereas the dependent variable changes according to the independent variable.
