Define control group.
Standard to which comparisons are made in an experiment.
Why are control groups important?
They are what we compare our data to, so we can see how ours differs.
What is an example of a good control group?
A good control group is testing the original variable then change one variable about it. For example test the firmness of a regular sized marshmallow, then again but with a jumbo marshmallow, then with a pink marshmallow. The control is the original basic marshmallow.
What is an error bar?
The range on top of bar graphs to show differences in data.
