What are groups?
Population collection of similar individuals.
What is a control group?
Identical in every way Except they will Not receive the manipulated variable. They will stay the same throughout
Why do we need these two groups? (Experimental & Control)
To get a side by side comparison with the original. Basis to observe & measure change.
Why is it important to get rid of Bias?
To get the truest study, one must remove previous opinions.
What are ways to remove Bias?
Placebo or fake pill or treatment
What is a single blind study?
Participants don’t know if they are the control or the experimental group.
What is a double blind study?
Researchers & participants dont know which group is which. These tend to be the most honest studies.

Correlation happens simultaneously, the relationship between them is coinsiding. (one goes up other goes up) (one goes down other goes down)
Cause & effect.
One variable causes the direct change in the other variable.
