What are independent variables?
Variables we believe will cause a change to another variable
What is the name of the variable that we believe the independent variable will cause a change to?
The dependent variable
What is the name of the variable that we believe will cause a change to the dependent variable?
The independent variable
What are dependent variables?
Variables that we measure
What is the name of the variable that is measured?

If we were investigating if the length of a word affected the number of words recalled, what would be the variable that we would be measuring? (i.e. the dependent variable)
The number of words correctly recalled
What are confounding variables sometimes known as?
Extraneous variables
What are extraneous variables another name for?
Confounding variables
What are confounding variables?
Variables that could cause a change to the dependent variable, even though we do not want them to
What, other than independent variables, can cause a change to the dependent variables?
Confounding variables
What, other than confounding variables, can cause a change to the dependent variables?
Independent variables
What are the two types of variables that can cause a change to the dependent variables?

What are the 3 types of variable that psychologists are concerned with in their research?
Independent variables, dependent variables, confounding variables
Define the 3 types of variable that psychologists are concerned with in their research.
- Independent variables = Variables we believe will cause a change to another variable
- Dependent variables = Variables that we measure
- Confounding variables = Variables that could cause unwanted change to the dependent variable
