Occurs when an extraneous variable makes it difficult to see the effects of the IV

A process for selecting participants whose characteristics reflect the characteristics of the population they were drawn

Occurs when a researcher's expectations influence the results of a study

The variable that an experimenter manipulates in order to observe its impact

Use of in-depth methods incl. conversations, interviews to understand the how and why of human behaviour

The variable that changes in response to another variable

Placing, 1st, 2nd or 3rd OR being allocated a Pass, Credit, Distinction, HD are examples of which Scale of Measurement

Any variables other than the IV that might influence the DV in an experiment

Statistics used to interpret data in an experiment and draw conclusions

Judgment inferred from statistics that that probability of observed findings occuring by chance is very low

A standardized measure of variability in data

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

Research performed over time with the same participants

The degree to which test results or evidence occurs repeatedly

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

Height, Weight, Reaction Time and Exam Score are all examples of which kind of Scale of Measurement?

The spread or dispersion of data, including the extent to which scores vary from the mean

Statistics helpful in organising and summarising (but not interpreting) data

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

Distribution of subjects in experiment where each has equal chance of being assigned to any group

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

The degree to which the test measures what it is supposed to measure

An instrument category used to measure aptitude and performance
