[IxDA Discuss] Asking questions to participants in a positive or negative way ?

[mark schraad]

What you are prosing is called semantic differential. Think very
carefully about the terms you use... it it not as simple as you might
think. getting those terms right is the single hardest part of this
technique and has the potential to radically skew your results. There
is quite a bit of information out there now that you know what to call
it.

The problem with most lickert scale surveys (not like it, 1 - like it,
10) is that the survey will be pre bias towards an aggregate score of
seven. It is really hard to get around that when people administer the
survey and people are taking it.
