The procedures needed to measure or manipulate the constructs
What is internal validity?

Logical analysis
What are the three options for assignments?
Random assignment to groups/conditions
Lack of random assignment
No assignment
What is external validity?
The validity of inferences about whether the relationship holds over variations in persons, settings, treatment variables, and measurement variables.
What is the definition of between-subject designs?
Individuals experience only one experimental treatment (i.e., one level of the IV).

Random assignment
Experimenter manipulates IV
Good control over other variables
There are nine threats to internal validity. What is the definition of maturation?
Naturally occurring changes over time could be confused with a treatment effect.
What are the advantages and disadvantages of Within-subject design?
Advantage: Each person serves as his/her own control
Disadvantage: Probably have to counterbalance

What is sampling and what is assignment?
Sampling – the manner in which subjects are selected to participate in the study
Assignment – if and how individuals are assigned to different conditions (e.g., experimental vs. control group)
What is the threat of validity?
Specific reasons why we can be partly or completely wrong when we make inferences on the basis of research.
