I posted this message a few days but lost access to that thread. Hence posting it again.

I have yearly data from 2004 to 2009 on a particular subjject. I have calculated the compound annual growth rate for the period. How can I test the significance of CAG using T test? Can someone give some material on how to do it in SPSS?

I'm not a statistics expert so I am wondering if someone can give some guidance on need sample size. Here's the scenario:

I have some distinct markets (e.g. LA, NYC, etc...) that we want to be able to compare to an overall national sample. Also would like to be able to compare the markets vs. markets (i.e. LA vs. NYC). If I use one of the sample size calculators I get that I need roughly 400 responses whether an individual city or national. So that would seem to require 400 national plus 400 per market. Problem is that there are over 10 markets making the cost of such a project prohibitive.

Does anyone have a sample size/distribution suggestion for doing such a project?

Thanks. ]]> General Research Discussion dnvrbw http://forum.researchinfo.com/showthread.php?5017-Sample-Size-Question http://forum.researchinfo.com/showthread.php?5016-Some-questions-regarding-tourism-survey&goto=newpost Wed, 09 May 2012 14:32:04 GMT Hello everybody!

I'm new in this forum and I would like to introduce myself. I come from Germany and currently studying in Cyprus Leisure and Tourism Management. For a course here I have to do a survey about Risk Perception in Tourism. It would be really great if some of you could have 5 minutes to just fill out the questionnaire online :) Just follow the link:

http://https://www.soscisurvey.de/risk-in-tourism

Now my question:

Is it possible that when I ask the first question about how risk taking you consider yourself, that I can later just turn it into numbers like 1-4? My plan is to compare the "means" by country. Lets say I draw a line and mark 1,2,3,4 on it. When the mean of one country is 2,3, can I just mark it on the line and than compare it with other countries?

Hope thats understandable :)

Thanks in advance! ]]> General Research Discussion Menix http://forum.researchinfo.com/showthread.php?5016-Some-questions-regarding-tourism-survey http://forum.researchinfo.com/showthread.php?5014-Number-of-factors-using-parallel-analysis&goto=newpost Mon, 30 Apr 2012 10:16:12 GMT Hi, this is my first post in this forum and I hope that someone can help me :) I am writing on a paper for my university and I am not really sure whether my interpretation of parallel analysis is correct.

this is my first post in this forum and I hope that someone can help me :) I am writing on a paper for my university and I am not really sure whether my interpretation of parallel analysis is correct.

After running this syntax (rawpar) in SPSS, I got the following result:

Actual Eigenvalue / Average Eigenvalue / 95th Percentile Eigenvalue

1) 3,33 / 0,70 / 0,84
2) 1,66 / 0,56 / 0,67
3) 0,71 / 0,45 / 0,53
4) 0,55 / 0,35 / 0,43
5) 0,40 / 0,27 / 0,35
6) 0,21 / 0,19 / 0,25

According to this paper: "Factors or components are retained as long as the ith eigenvalue from the actual data is greater than the ith eigenvalue from the random data."

-> Retain 5 factors because 3,33 > 0,84; 1,66 > 0,67 ....

However, eigenvalues 3,4,5 are smaller than 1. Does it mean that only 2 factors should be retained?

Please advise how many factors should be retained :) Thank you very much! ]]> General Research Discussion PleaseAdvise http://forum.researchinfo.com/showthread.php?5014-Number-of-factors-using-parallel-analysis http://forum.researchinfo.com/showthread.php?5013-test-of-significance-of-compound-annual-growth&goto=newpost Wed, 25 Apr 2012 18:13:56 GMT Hi friends, I have the annual data for a five year period for which I have calculated compound annual growth.
