correlational research


Behavior related study, a type of validity

convergent validity


I am an experiment and I have the most____

control

Also known as ex post facto study

causal comparative

baseline designs


In single subject research, there are two type of designs I can be used in

within or within component of mixed subject design


In research, this means to enhance the welfare of your participants

beneficence


Do as much good

beneficence


I only measure my participants one time

Between subjects design


I don't fit neatly into any category but I employ many data collection techniques for descriptive data

Case study


I use intact groups in my sampling

Cluster random sampling


Do two or more groups known to differ also differ with respect to a 2nd variable

Comparative Research


I vary systematically and am unwanted

confounding variable


I am a representative sample of material in a test

Content validity


If a test only contains one question, it lacks this?

content validity


I tell the strength and direction of relationship between 2 variables

correlation coefficient


How much variance in one variable that can be accounted for by knowing a 2nd variable

correlation coefficient


Done to deal with order effects

counterbalance


measure of comparison

criterion validity


Done after study to participants

debrief


Give clues to participants

demand characteristics


measures what actually exists with one single variable

descriptive research


Nobody knows anything about the study

double blind


Directly verifiable

empirical


another name for causal comparative

ex post facto


Find something because you expected to find it

experimenter bias


Treat one group different than another to get results you want

Pygmalion effect or experimenter bias


How well your findings apply elsewhere

external validity


Look of the test

face validity


Experimental study involving 2 or more independent variables

factorial design


Goals of research

define, explain, predict, change or control

Hypothesis


Prevent reactivity with this

cover story

cross sectional study


theory to hypothesis, general to specific

deductive reasoning


the variable that is measured

dependent variable


Report what exists with respect to one variable

descriptive research


behavior related study where you don't want a correlation

discriminant validity


Learn about the culture of an intact group, detailed and ongoing

ethnographic


Does one variable affect or cause a 2nd variable?

experimental


Can two groups differ because of IV

Experimental


Manipulation before measurement

experimental


Affected by sampling technique and experimental realism

external validity


I vary randomly and don't affect IV

extraneous variable


Be true to study, obligations

fidelity


Reactivityanother name

Research that is counted or measured

quantitative research


Use of intact groups to do research

quasi experiment


The most popular way to do research

quasiexperiment


Looks like the population it was taken from
