Hunted through Prism's Analyze menu for ANCOVA? It isn't there, and GraphPad's own FAQ confirms they've never shipped one. Prism can still do it, through two documented routes most users never find: the simple-linear-regression slopes test for the parallel-slopes assumption, and multiple regression with dummy-coded groups for the adjusted comparison. Here are both step by step, plus an honest comparison with describing the same analysis in plain language instead.

Your treated and control wells started at different confluence, so comparing endpoints with a plain ANOVA measures your treatment effect plus the head start. ANCOVA fixes that by adjusting for a continuous covariate, and usually buys power too. This step-by-step ANCOVA protocol runs 24 numbered steps from covariate choice through reporting, with the assumption checks in the order they need to happen, including the parallel-slopes test most people skip.

An audit of 200 published animal studies found only 22% had replicated the right thing, and 46% counted repeated measurements of one biological unit as independent samples. That error, pseudoreplication, inflates your n, shrinks your error bars, and manufactures significance that won't replicate. Here's what separates technical vs biological replicates, why the mistake inflates false positives, and what actually counts as a biological replicate in cell culture.

A no-fluff, step-by-step scratch assay imaging protocol for images your software can actually measure. Twenty-six numbered steps take you from pixel calibration and Köhler alignment, through Time 0 capture with locked exposure, to returning to identical fields at later time points. Includes an equipment table, an acceptance-criteria checklist to run before you analyze, and a troubleshooting table mapping every common symptom to the step that fixes it.

When medical residents were surveyed on interpreting a p-value, 88% were confident they understood it and 100% got it wrong. That gap is why p-value mistakes survive peer review: nobody thinks they're making one. This piece covers the five most common errors in biomedical papers, several measured at scale in real journals: the inverse probability fallacy, the replication fallacy, 'trending toward significance', p-hacking, and treating 0.05 as a bright line.

A no-fluff, step-by-step cell imaging protocol for microscopy images you can actually quantify. Eighteen numbered steps take you from Köhler setup and pixel calibration, through setting exposure on your brightest sample so nothing saturates, to acquiring the whole set under locked, identical settings. Works for brightfield, phase contrast, and fluorescence. Includes an equipment table, an acceptance-criteria checklist, and a troubleshooting table mapping each symptom to the s

Your p-value can confirm an effect is real and say nothing about whether it's big enough to matter. Effect size answers that second question, and for a two-group comparison Cohen's d is the standard measure: the mean difference divided by the pooled standard deviation. This guide covers how to calculate and report Cohen's d, why to report it alongside every p-value and confidence interval, and how to interpret it without leaning on the 0.2/0.5/0.8 benchmarks that often don't
