Design solution

I'm having an argument with my mate, this is it below

Group A. Work at certain job and I want to test and see if there job makes them more extrovert

Group B. Are the control group by which you will measure the base line. This also work full time and are of the same age

Independent Variable = Extraversion
Dependent Variable= Career

Both groups will be tested on the big 5 personality test to determine results

what type of design is this study and what are the variables?

What's the difference between Group A and Group B?

Group A work in a call centre
Group B work in an office

I want to test both groups to see if working in a call centre makes group A them more extroverted,

You're kind of coming from a flawed premise there, because it's highly likely that more extroverted people will be drawn to jobs in which they have to interract with the public. In that case, it's impossible to see if something "makes" them more extroverted. The only way you could measure that is with a longitudinal study (say 1 year) whereby you test their introversion/ extroversion before they start working in the call centre, then art multiple points you re-administer it, and compare the results over time.

I told him that but he still argues that your study will be an experimental design, independent variable extroversion, and dependent Variable working in a call centre

Well with this approach you can probably establish that the people who work in call centres are more extroverted, but you won't be able to establish that working there made them that way (rather than extroverted people being attracted to the work, or having a better chance of being offered the job etc)

If you are comparing call centre group to a 'control' group, then you are looking for a correlation between call centre and extraversion. That is all. You can make absolutely no inferences about cause and effect.

If you were to test the two groups over time, then perhaps you could infer cause and effect.
