Making inferences: 
A statistical statement of how likely an obtained result occurred by experimental manipulation or by chance

Description
Case Study
A technique in which one person is studied in depth to reveal underlying behavioral principles.

Survey
A technique for ascertaining the self-reported attitudes, opinions or behaviors of people usually by questioning a representative, random sample of people.

Exploring cause and effect

Like other sciences, experimentation forms the backbone of research in psychology. 

Correlation 
Independent Variable
- a factor, manipulated by the experimenter, and whose effect is being studied
- breast feeding is the independent variable. 

-Dependent Variable is a factor that may change in response to independent variable. In psychology it is usually a behavior or a mental process.
 
For example, in our study on the effect of breast feeding on intelligence. Intelligence is the dependent variable.

Scatterplot is a graph comprised of points generated by values of two variables. The slope of points depicts the direction, and the amount of scatter the strength of relationship.


Illusory Correlation: The perception of a relationship where no one exists Parents conceive children after adoption. 

Hindsight Bias
- The "I knew it all along"
- The inclination after an event has occured to see the event as having been predictable.

Order in random events: Given random data we look for order, for meaningful patterns.
