Correction to Graph for Trends at SIUC Part 1

with one comment

A reader left a comment criticizing a graph in a previous post about enrollment and employment trends at SIUC. The reader wrote:

Your scale on the professional non-faculty graph is misleading. Unlike most of the other graphs, the scale on the professional non-faculty graph starts at 0, and it looks like it barely changed. Really it was the one of the biggest changes on all of these graphs. The professional non-faculty increased from about 1175 to nearly 1600, a larger increase than the faculty increase from 1525 to about 1650.

The original graph was not an attempt to mislead. In fact, in that post I recommended reducing staff in that category of employment. Still, the reader was right. I replaced the graph.

For comparison, here are the original and replacement graphs side by side:

Both graphs use the same data, but the scale is different. The replacement graph (right) better expresses the incredible growth in the professional non-faculty category over the last ten years.

Thanks to the reader who pointed out the lousy graph.

Comments are welcome.
