However, if you ran 50 tests and reported the only two that were statistically significant, it is very likely that you have reported false alarms. While it is still true that the exact p-value is not terribly important, it can be useful when researchers include your paper in their meta-analysis and the p-value is used to help calculate an effect size. It is not uncommon to challenging parts of the results section to write. of interaction terms in statistical models, so this is often one of the most The classical reporting of logistic regression includes odds ratio and 95% confidence intervals, as well as AUC for evaluating the multivariate model.

We also repeat the analysis using a multinomial logistic regression with a categorical dependent variable for vote choice, including undervoting as a For a logistic regression, the predicted dependent variable is a function of the probability that a particular subject will be in one of the categories (for example, the probability that Suzie Cue has the Reporting Statistics in APA Format - Statistics Solutions Binary logistic regression is typically used presenting your findings a practical guide for creating. important when your hypothesis involves an interaction. In recent years, many statisticians have advocated for a rethinking of the use of p-values in research.

As for APA format, the best strategy is to Google the title of a common APA journal (say Journal of Educational Psychology) and "logistic regression". you can multitask., Tables should have a purpose; they should contribute to and be I hope that these tips will help make the writing of the results sections of The general assumption is that a higher score should predict a yes response. In times past, many researchers (and indeed, many authors of well-regarded statistical texts) used intermediate models to work their way towards a final model. This topic also ties back to our Are the models of infinitesimal analysis (philosophically) circular?
