The dataset includes the data obtained for the randomized controlled study conducted from September to October 2018 in Universidad Nacional de La Matanza, Buenos Aires, with the aim to confirm efficacy of the web-based platform e-status in Probability and Statistics courses. Results appear in the manuscript Measuring the effectiveness of online problem solving for improving academic performance in a probability course, from the same authors. Hopefully published in the coming months. Students data have been anonymised, by removing ID numbers. Moreover, gender of students has been deleted, and age categorized into one of three classes (until 22 years, between 23 and 25, more than 25).
