X1, X2 Y Technique Abbreviation
Interval Interval Multiple regression analysis MRA
Research question: Can Y be predicted from X1 and/or X2?
e.g. Can depression be predicted from life events (X1) and/ or coping (X2)?
Nominal Interval Analysis of Variance ANOVA
Research question: What is the effect of X1 and X2 on Y?
e.g. What is the effect of leadership style (X1) and job type (X2) on job satisfaction (Y )?
Nominal and Interval Interval Analysis of Covariance ANCOVA
Research question: What is the effect of X on Y after correction for C?
e.g. What is the effect of video gaming (X) on spatial visualization ability [Post-test (Y) and Pretest
(C)]?
Interval Binary Logistic regression analysis LRA
Research question: Can Y be predicted from X1 and/or X2?
e.g. Can passing an exam (Y) be predicted from the number of study hours (X1) and number of
lectures attended (X2)?
Remarks: X1, X2 can also be binary BUT if Y is binary, then LRA
