Definitions
This is the term for when results of a study can be generalized beyond the scope of the study
External validity
This is the role of a sample
to be representative of the population
For external validity you need to be able to generalize results how?
from sample to population, measure to measure, to the real world
This is a type of sampling when the researcher cannot identify how likely someone is to be selected for the sample
Non-probability sampling
This is a person who is involved in a study but that is not known to participants. Usually they will interact with the participants in some way
Confederate

Psychological realism
This type of bias means that some people did not respond to the survey and the researchers take the information they gathered as the factual results.
non response bias
This is the name for the population you are trying to say something about.
target population
This type of sampling involves the participants recruiting other people they know to be in the study

Does it extend: I want to look at LVC students and how they think. I ask every single professor to fill out my survey.
NO

Proportionate stratified
4 things are needed for internal validity. Name them
manipulation, outcome measure, comparison, experimental control,
When non responses differ from those who responded
non response bias
I stand on the street and ask anyone who walks by what their favorite hockey team is. Is this a good way to get data on how NHL fans feel about their opposing team?
no. not one bit
Does it extend: I want to look at which ice cream flavor Americans like most. I send a survey out to every American registered to vote
