Most bench scientists reach for a t-test or ANOVA by reflex, but plenty of real experiments have a continuous dose, groups that differ at baseline, or nuisance variation eating the power. Multiple regression handles all three, and ANOVA and ANCOVA turn out to be special cases of it. This guide covers when regression earns its place, how to read coefficients honestly, the two covariate mistakes that invalidate an analysis, and why dose-response needs a 4PL curve, not a line.

Are outliers ruining your datasets? In biomedical research, distinguishing between biological variability and technical error is critical. This guide compares the traditional Grubbs’ Test against the modern ROUT method, explaining why the ROUT method's False Discovery Rate (FDR) approach is superior for detecting multiple outliers in pre-clinical data. Learn the exact protocols for GraphPad Prism and R to clean your data scientifically and avoid P-hacking.
