I work in a company that gathers work environment surveys. When a survey is done we create reports that are handed out to the managers in the company to show where they need to focus their efforts and such.
In these reports we show a comparison of the variance of the calculated group compared to the variance of a reference population. We "normalize" this score on a 0-100 scale. (The in-code calculation gives another scale from -inf to +inf, but for simplicity we say that 0 is 50, and just chop off everything over 100 and under 0.) Our biggest problem is that our customers gets very conscious of the actual number. Even though we try to tell them that a high/low number isn't necessarily bad, it just shows how your groups variance compares to the reference populations variance.
We are thinking of moving away from showing the number in the end-user report, and going for a visual representation of "high", "normal", "low" variance instead. But I can't figure out any good visual representation of it. It needs to be kind of neutral looking, but still show something... (.. i know ..)
Does anyone have any suggestions on how this could be achieved?
