Operational Definition
A statement that defines the exact operations or methods used in research.

Hindsight bias
the tendency to believe, after learning an outcome, that one would have foreseen it (I knew it all along!)*

Applied research
any of several branches of psychology that seek to apply psychological principles to practical problems of education or industry or marketing etc*

The degree to which they accurately represent the topic being studied.

The degree to which the data are stable and consistent.

selecting participants for research.

Confounding variables

Scatter plot
a graphed cluster of dots which represent the values of two variables. (Positive = directly proportional, negative = indirectly proportional, closer to zero = weak/no correlation)*

Normal Curve
a symmetrical, bell-shaped curve that describes the distribution of many types of data.*
