Hey guys!

I made this animated visualization for a school project. It compares how the average GPA of students admitted changed over time for the different UC schools.

One thing to note is that UC Merced does not appear until 2005. This is because UC Merced was founded on September 5th, 2005, so there is no data on admissions before that date.

I used Plotly and got the data from the University of California’s published data. https://www.universityofcalifornia.edu/about-us/information-center/admissions-source-school

Fun! Any insight into the influence of changes in maximum GPA over that time?

There is probably influence of "Grade Inflation" on the overall increasing admittance GPA for these schools.

Here's an article by Inside Higher Ed about grade inflation(incl. overall GPA) both in Colleges and High School:

I would have hoped for that author to mention the phenomenon of schools switching from a 4 max grade point to 5. In 1994, at many schools straight A’s full of AP classes would get you a 4.0.

You are right. I'm not 100% confident on this whether they adjust unweighted GPA to weighted for those years. I know there are some 4.0+ GPA(so weighted) schools for 1994, but whether or not the other datapoints are adjusted is definitely something to look at.
