Unrelated t-test
What inferential test do you use for a correlation with ordinal data
Test of correlation Spearman Rho (rho)
What inferential test do you use for a correlation with interval data
Test of correlation

What inferential test do you use for a non-experiment e.g. observation with nominal data
Test of Association
Chi-squared test (x2)
What is meant by demand characteristics?
Features of an experiment which subconsciously influence the participants’ performance
What is meant by order effects?
If the participants perform all the conditions they might be fatigued or bored
What is meant by quantitative
Type of data expressed in numbers
An experiment which takes place in the participants’ environment when the IV is not manipulated by the experimenter
Natural experiment
Hypothesis that predicts the direction in which the DV will change when the IV is manipulated
Directional (One-tailed)
Reliability
The extent to which measures are consistent
Operationalisation
Expression the IV and the DV in a way that can be measured
