I have data from two surveys. One survey was completed on 900 people before a certain event happened, and then a second survey was completed on a further 900 people after an event happened.
I need to calculate the % difference between the two whilst looking at the demographics of the individuals. E.g. difference between gender, ethnic group, age groups, etc. I also then have to calculate the p-value of each of these to show whether the difference between the pre and post surveys is significant. I'm guessing that a Chi-squared test is best for this, but how do I go about doing this in excel? Surely there's a simply way of just calculating the p-value of the difference between the two surveys? -- ---------------------------------------------------------------------------------- Some important links for excel users: 1.
