This dataset included student data from high school comparing the student achievement throughout the years. Student achievement was indicated as test scores, final grades, GPA of students, and whether the student passed or failed. The analyses were estimated in the SPSS 29 program. The data collected was from a sample (N) of 105 students in a specific high school. The range is 2.86, considered high if the GPA scale is out of 4. The mean is 2.7789. The standard error (SE) was 0.07454, and the standard deviation (SD) was 0.76380, which indicates a correlation between student achievement relative to GPA.
