An explanation using an integrated set of principles that organizes observes and predicts behaviors or events.

A testable prediction often implied by a theory.

Thinking that does not blindly accept arguments and conclusions. Rather, it examines assumptions, discerns hidden values, evaluates evidence and assesses conclusions

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

An explanation using an integrated set of principles

A testable prediction, often implied by a theory.

All the cases in a group being studied, from which samples may be drawn.

An observation technique in which one person is studied in depth in the hope of revealing universal principles.

All the cases in a group being studied, from which samples may be drawn.

A sample that fairly represents a population because each member has an equal chance of inclusion.

A statistical index of the relationship between two things.

The perception of a relationship where none exists.

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

The perception of a relationship where none exists.

A factor other than the independent variable that might produce an effect in an experiment.

In an experiment the group that is exposed to the treatment, that is, to one version of the independent variable.

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

A technique for ascertaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group.

A testable prediction, often implied by a theory.

A statistical index of the relationship between two things (from -1 to +1).

The perception of a relationship where none exists.

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

A sample that fairly represents a population because each member has an equal chance of inclusion.

The outcome factor; the variable that may change in response to manipulations of the independent variable.

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

Experimental results caused by expectations alone.

A factor other than the independent variable that might produce an effect in an experiment.

Experimental results caused by expectations alone.

The experimental factor that is manipulated; the variable whose effect is being studied.

The perception of a relationship where none exists.

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

Observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation.

A statistical index of the relationship between two things (from -1 to +1).

A statistical statement of how likely it is that an obtained result occurred by chance.

The arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores.

A computed measurement of how much scores vary around the main score.

The enduring behaviors, ideas, attitudes, and traditions shared by a group of people and transmitted from one generation to the next.
