A tibble with 193 rows and 2 columns. The columns represent the variables gpa and study_hours for a sample of 193 undergraduate students who took an introductory statistics course in 2012 at a private US university.
gpa - Grade point average (GPA) of student.
study_hours - Number of hours students study per week.
GPA ranges from 0 to 4 points, however one student reported a GPA > 4. This is a data error but this observation has been left in the dataset as it is used to illustrate issues with real survey data. Both variables are self reported, hence may not be accurate.
Collected at a private US university as part of an anonymous survey in an introductory statistics course.
