What are constant and controlled variables?
Constant/controlled variables are variables that remain the same throughout an experiment. For example, if you wanted to see whether light affected how well plants grow, you would feed them equal amounts of water, so that the only variable affecting their growth was light exposure.
Are constant variables and independent variables the same?
No they are not the same. A constant variable keeps going at a constant rate.
The variables in an experiment that stay the same?
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
Do you have to use the same variables for all equations when creating a system of equations?
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.
What does Correlation of plus 1.00 mean?
It mean that there is no correlation between the two variables. The variables are the same.
