The percentage of college freshmen who re-enroll for their sophomore year is an excellent indicator of the quality of the college. From a parent’s perspective, you want to avoid colleges with low retention rates. As a college administrator, increasing retention is a sure way to increase tuition revenue. Retention varies greatly among colleges as the chart below shows with the 37 private colleges in Massachusetts ranging between 52% and 98%. The data were compiled by Shorelight Education.
A stacked bar chart works well to display retention data by college. I used a few tricks to make the chart more informative:
- Slanted bar labels allows you to easily read the chart, even though there are 37 bars (colleges)
- Axis break shortens each bar, focusing the reader on differences across the colleges
- Remove the Y axis as it didn’t add any important data to the chart and provided more room for each bar
- Color the colleges with high retention and low retention and bold their names to highlight good and poor performance
- Add an average line to indicate the middle of the retention distribution and allow for comparing each college to the average.
