What is a Control Group?
A group that is used to compare the experimental against.
What is an experimental group?
A group that is being tested, it has the independent variable being changed.
Which graph axis would the independent variable go on?

Which graph axis would the dependent variable go on?
The Y Axis
I am testing whether or not fertilizer will boost the growth of my plants, what is the independent variable?
The independent variable is fertilizer usage.
I am testing whether or not fertilizer will boost the growth of my plants, what is the dependent variable?
The dependent variable would be the growth of my plants.
What would be the control group if I were testing whether or not fertilizer would boost the growth of my plants?
The plants that do not use the fertilizer.
What would be the experimental group if I were testing whether or not fertilizer would boost the growth of my plants?
The plants that are using the fertillizer.
What is the difference between the independent variable and the dependent variable?
The independent variable is what is being tested/changed and the dependent variable is what changes as a result of that change.
If error bars overlap what does this mean for the two groups?
They are very similar to each other.
If the error bars don’t overlap, what does this mean for the two groups?
They have little similarities and a lot has changed.
Why do we use control groups?
So that we can compare the experimental group to the natural process.
