Hi!

When you say "mean 4.00" and "mean 4.61", what was the survey instrument? Am I correct in assuming that the questions were structured as...

Agree or disagree: you like to read.
- Strongly disagree (1)
- Disagree (2)
- Neutral (3)
- Agree (4)
- Strongly agree (5)

Is that correct?

what would have been a normal distribution.......

thanks for all your help....it was worth the \$60.00....

Expert:  Eric M. replied 5 years ago.
A normal distribution occurs when the values are evenly distributed around the mean. So, for example, if the average of the survey had been 3 and the standard deviation had been 1, then that would suggest that just as many people replied "2" (one standard deviation below three) as replied "4" (one standard deviation above the mean). Usually, it wouldn't be possible to tell whether a distribution is normal solely on the basis of the information here, but because we know the maximum survey response value is '5', we know that there can't be answers above 5.

Certain properties of the normal distribution still apply (we can imagine the theoretical values above 5 being 'collapsed' into 5, so that 5 represents what would have been the number of responses of 5, 6, 7, 8, 9, etc.), but it's difficult to predict which properties specifically are still applicable.
