(e.g. when one person out of a hundred rates something as a 10, it shows up as a 10, whereas the weighted results
would show that only 1 person out of a hundred rating it as a 10.)
Unfortunately (and as others have implied) there
may be too many factors (e.g. age, race, etc) at play to make a simple average useful. Someone else in another
thread tried to collect more data to perform a multivariable analysis. This may be the way to go. Collect age,
race, build, etc along with these ratings. Pop the data into a statistical software like Minitab and voila! If
someone decides to go this route - please set up a spreadsheet first, so that all the data is in the same format
from the get-go.
And by the way:
NPA 8 (I love getting the lady who cuts my hair all "upset" with NPA)
AE
6
I have also tried some mixes with mixed results
peace to all
