This markdown includes data from Chemistry students in classes CHM 121, CHM 221, and CHM 222 in Fall 2019 and Fall 2020. Data from the Spring 2020 semester were excluded due to the changes in university classes necessitated by the Covid-19 pandemic. Students who dropped and who completed the class are both included in the data.
Students’ average grades are calculated by averaging the grades (0-100) of their 4 or 5 exams.
At the time of each exam, participants were asked what their goal grade for the class is.
Prediction Error is the difference between the grade a student predicted that they got on an exam and the actual grade they got on that exam. A negative prediction error means that the predicted grade was higher than their actual grade, meaning they overestimated. Participants are asked for their grade prediction on the day of the exam.
In the plots and analyses below, data from students who identified as “Native American” or “Native Hawaiian or other Pacific Islander” were omitted due to small group sizes (2 students and 1 student, respectively). Data from students who identified as “Other” were not included as a unified group due to the heterogeneity of races specified.
