Bio

I’m Marjan Bakker and I’m an assistant professor at the Methods and Statistics department at Tilburg University. I want to improve science by investigating problems and possible solutions. I’m interested in reporting errors, the use of questionable research practices, statistical power, outliers in data, publication bias, and preregistration. Currently, I’m mainly working on some larger projects on preregistration and on a project to replicate Mahoney’s seminal study on publication bias (for which we got a NWO replication grant).

I also teach courses on regression analysis to psychology students (bachelor) and multilevel analysis to students from the research master and I like to work together with researchers from other departments.
