Transcript of Differences between Independent Variable, Dependent Variable, Constant, and Control c:

A constant variable is a variable that can are kept to be the same. Constant variables allow for a fair test.
For example, type of battery, time left at each temperature. Constant Variables ;} A dependent variable is a variable that you measure. It is also called the responding variable. Goes after the THEN statement.
Fore example, IF the storage temperature decreases, THEN the battery life will increase BECAUSE the chemical reaction occurring in the battery slows down.
Graphed on the Y- axis.
D- Dependent
R- Responding
Y- axis
Dependent Variable ;] Independent Variables :D A independent variable is a variable that can be changed. Independent variables are also called the manipulated variable. Independent variables also go after the IF statement.
For example, IF storage temperature decreases, THEN battery life will increase BECAUSE the chemical reaction occurring in the battery slows down.
Graphed on the X- axis.
M- Manipulated
I- Independent
X- axis
Control Variables :P Control variables are variables that have nothing done to it so it can be used for comparison.
