| Graphic Results of an Audience Voting
Session: The Bell Curve |
|
| Typically, a very high level of agreement exists
when your interactive question's graph forms a bell curve.
You will see that the
center column (or columns) are the tallest with a rapid fall off to both
sides, forming a bell shape. |
|
|
 |
|
| The taller and narrower the bell, the
more agreement you have within the audience. This
interpretation is especially valid when the scale is based on a general
continuum. For example, you may be asking for a rating of importance
where 1 is not at all important and 7 is critically important. |
|
| With this type graph on screen, the
presenter should focus on the extent of agreement. If you are
surprised by the number of outlying votes, you might want to cut
(filter) the results by one of your demographic questions. |
|
| If you call for discussion on bell
curve results,
you are likely to find some strong opinions. However, don't put
anyone on the spot. It is better to say "can anyone tell me why
some of us felt this is unimportant?" than it is to say "would someone
who feels this is unimportant please stand and tell us why."
Generally though, because your audience is in agreement, you don't need
to spend much time on the issue when you see a bell curve. |
|
| Another very common type of graphical
pattern is the 'skewed distribution'. |
