Hello,
I have asked the following questions on a survey:
1) Is drink A healthy?
2) Is drink B healthy?
I would like to compare (statistically) the proportion who said 'yes' to Q1
to the proportion who said 'yes' to Q2. I can only find references comparing
proportions from independent samples - is it valid to use an independent
t-test on proportions that are based on the same sample of people? If not,
what approach should I use?
Thanks in advance for any comments,
Beth
You may leave the list at any time by sending the command
SIGNOFF allstat
to [log in to unmask], leaving the subject line blank.
