Detailed Summary

On January 2nd, 2019, Educational Technology Services released reports for Fall 2018 end of term online evaluations. It has been brought to our attention that the mean value displayed in the table below each quantitative question in those reports is showing an incorrect value.

The average/mean is displayed in two places for each quantitative question: a bar graph displays “your average”, and the statistics table below displays the “mean” value. These two numbers should be the same, but currently, the average displayed next to the bar graph is correctly calculated, while the mean below is incorrectly rounding down to the nearest integer.

Instructors should refer to the average value, shown next to the bar graph, and ignore the mean value displayed in the table.

As of January 9, 2018, we have updated all reports, addressing the discrepancy, and are now reaching out to impacted instructors and department administrators.
