Types of Correlation:

               -Positive: variables go in the same direction

               -Negative: variables go in the opposite directions

    Ex: There's a negative correlation between smoking cigarettes and living a long healthy life. 

Blind Study: the subjects are unaware that they are being conducted an experiment on.

Double-Blind Study: neither subjects nor experimenters know which group is control or experimental.

Correlation: suggests a relationship between two variables but it does not establish causation.

-Descriptive Statistics: describes the results of research

-Inferential Statistics: inferences or draw a conclusion.

-High Standard Deviation: means scores are spread out

-Low Standard Deviation: means that scores are clustered together
