Warning: G-Power is a time stealer
Sunday, March 7th, 2010So today I finished up the 11th activity in RSH9103QNB and got ready for the 12th as outlined in the syllabus:
Consider your study, conduct a mock power analysis using G*Power. Include the results of your power analysis in a word document. Submit these results along with a brief paragraph, approximately 250 words, stating the role of a power analysis in your dissertation, and why you must include a power analysis in your paper.
Sounds pretty straight forward, but little did I know it would take me way too long to even get the program up and running and start working on the assignment. The syllabus directed me here and so I read up on G-Power. G-Power is a tool that a researcher can use to identify the sample size most appropriate for the study, i.e. one that provides enough of a sample, but not too much of a sample. The idea is to find at what level is the size meaningful.
Well, I downloaded G-Power 2 and then after installation a little note pops up and tells me that G-Power 2 cannot run on my Vista system…that is, after it went through even setting up some “missing files” to run the program. So I went back to the website and downloaded G-Power 3. This program also tells me that I am missing some files so I have to wait for those to download. Then the setup informs me that I have to reboot, then it finishes setup. Then I can’t find the program on my computer.
Five minutes later I find the program and run it. And I am not sure what I am supposed to do with it.
So I spend an hour looking up the two pdfs the syllabus gives me, plus reading the tutorials on the G-Power website, plus doing a Google search for any information that I can find about power and G-Power.
I end up spending way too much time just prepping for this activity. I haven’t even started writing yet. Of course, the activity is only 250 words or about a page, but I have to understand the program and G-Power before I can write even a word!
