AP Psych Unit 1B: Research Methods

Which of these correlation coefficients shows the weakest strength of relationship?

Effects that occur when subjects experience change due to expectations (or to "fake" treatment)

A larger group from which a sample is drawn and to which the researcher wishes to generalize

A statement about the expected relationship between two or three variables (what will be tested)

Statistics helpful in organizing and summarizing (but not interpreting) data

Statistical procedures used to interpret data in an experiment and draw conclusions

A descriptive statistic & measure of central tendency; exact halfway point of data distribution

Exists when a sample is not representative of the population from which it was drawn

This technique involves studying the spontaneous behavior of participants in natural surroundings

A statistical procedure that combines the results of many studies

The score that occurs most frequently

Research method in which IVs are manipulated and which permits causal interpretation

Which is not related to a survey method?

These are variables that make it difficult to determine the effects of the Independent Variable

The group in an experiment that is exposed to manipulation of the independent variable

The variable that results from the manipulation in an experiment

The statistic that indicates the degree and direction of relationship between variables

The arithmetic average

This occurs when a researcher's expectations influence the results of a study

Term used  to indicate whether or not the difference between groups can be attributed to chance

An in-depth, generally subjective, investigation of an individual subject

A condition or event that an experimenter manipulates in order to observe its impact

Procedure in which each participant has the same probability of being assigned to a particular experimental condition.

The group in an experiment that is not exposed to manipulation of the independent variable

A link or association between variables such that one can be predicted from the other

Statement of the procedures or ways in which a researcher is going to measure behaviors or qualities

Variables other than the independent variables that could influence the dependent variables in an experiment

This is used to guard against experimenter bias & the placebo effect.
