Sampling
The difference in scores that occurs when we test a sample drawn out of the population.
What is sampling error?
When a question on a survey is actually two questions in one.
What is a double-barreled question?
The variable that is used to predict the outcome variable.
What is the predictor variable?
A design in which participants receive all levels of the independent variable.
What is a within subjects design?
A variable when measured in whole units or categories that are not distributed along a continuum.
What is discrete?
A sampling technique that involves choosing individuals from the population at random where each individual has an equal chance of being selected?
What is a simple random sample?
The branch of Psychology that deals with establishing that the results of a survey are valid and reliable.
What is psychometrics?
When a variable that is not of interest in a study may explain the results of a study.
What is the 3rd variable problem?
A technique that can be used to control for order effects.
What is counterbalancing?
Non-ordered category responses
What is a nominal data?
A sampling techniques that involves choosing individuals from the population such that individuals are chosen from pre-existing groups.
What is a cluster sample?
A closed-ended response scale that has numbers that range from not very to very much.
What is a Likert scale?
The number of groups from which the measures in a correlational study are collected.
What is one?
A technique that can be used to control for group differences in a between subjects design.
What is randomization?
When a scale measures the behavior it was intended to measure.
What is construct validity?
The sampling techniques that is likely to create the smallest amount of sampling error.
What is simple random sampling?
A strong, positive relationship between scores on a new survey and scores on a previously validated survey on the same topic.
What is criterion related validity?
Correlational studies are not well suited to answering these types of questions.
What is causal?
Any value or characteristic that can change or vary from one person to another or from one situation to another.
What is a variable?
Indicates how similar scores on the different items of a survey are to one another.
What is internal consistency?
The sampling techniques that involves choosing individuals from the population such that individuals from the population who volunteer are selected.
What is a haphazard/volunteer sample?
A measure of internal consistency that takes the average correlation between scores on all pairs of items on a survey.
What is cronbach's alpha?
When you cannot determine which variable came first.
What is the problem of directionality?
When there are two levels to the independent variable.
What is a bivalent design?
Participants assigned into groups based on subject variables.
What is a quasi-experiment?
