We gathered data from 2.162 Dutch high school students, after (pre-registered) exclusion criteria 2.064 students remained. Responses of those 2.064 students are included in the stored dataset. With this data we test the theory that gender stereotypes can lead to deteriorated math performance for female students, but not for male students. Students participated in an experiment: Students in the experimental condition were exposed to stereotype threat, for students in the control condition stereotype threat was removed. After the manipulation students finished a math test. The main research question is whether the four groups (experimental condition x gender) differ in performance on the math test.
