Analyzing Variability in Student GPAs by Major

Very Hard Data Analysis Interpretation Of Data

A university conducted a study on the academic performance of its students across different majors. The table below summarizes the average GPA and the standard deviation for students in five different majors.

Major	Average GPA	Standard Deviation
Engineering	3.2	0.5

Based on this data, the university is trying to evaluate which major shows the least variation in student performance. What can you conclude from the standard deviations provided?

Biology shows the least variation in GPA since it has the lowest standard deviation.

Engineering shows less variation despite a similar average GPA compared to History.

History has a lower average GPA but a higher standard deviation, indicating more variation.
