A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other is called a

• measure of central tendency

• coefficient

• inferential statistic

• correlation

Define a double blind procedure:

• A statistical procedure that identifies common factors among groups of items

• An experimental procedure in which both the research participants and the research staff are ignorant about whether the research participants have received the treatment or a placebo.

• Any effect on behavior caused by the placebo, which the recipient assumes is an active agent, given to the control group in an experiment.

• A statement of the procedures used to define research variables.

In an experiement, this is main factor that is being studied, the "if" part of the study.

• distribution

• confounding variable

• independent variable

• correlation

In an experiement, this is the behavior or outcome of the study.

• dependent variable

• confounding variable

• independent variable

• correlation

Three descriptive methods of correlational studies in psychological research.

• experiements, correlations, case studies

• dependent variable, case studies, inferential statistics

• naturalistic observation, experiements, case study

• case studies, naturalistic observation, surveys

A graphed cluster of dots, each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables.

• scatterplot

• postive correlation

• survey results

• inferential statistics

The tendency to believe, after learning an outcome, that one would have foreseen it.

• sampling bias

• hindsight bias

• the random effect bias

• single blind procedure

Assigning participants to experimental and control conditions by chance, minimizing preexisting differences between those assigned to the different groups.

• random sampling

• double blind procedure

• random assignment

• random mugging

In an experiment, the group that is not exposed to the treatment being studied.

• experiemental group

• random sampling

• control group

• confounding variable

The perception of a relationship between two factors where none exists

• dependent variable

• illusory correlation

• direct correllation

• descriptive statistic
