research analysis confusion. Please help.
Hi all,
I have managed to get myself very confused.
I'm trying to work out what analysis to use on a correlational design with one IV and 3 DV's.
I thought I had it worked out with a MANOVA but I just read that you can only use a MANOVA
If the IV is categorical and mine is continuous (amoubt of time spent).
my DVs are 3 continuous measures of wellbeing.
Going crazy trying to work this out as nothing seems to fit.
I would really appreciate any help or direction anyone could provide.
Many thanks x

Re: research analysis confusion. PLEASE HELP!
how many levels does the iv have? and how many ivs do you have  is it just 1?

Thanks for your reply, I have one continuous IV (amount of time spent in hours) so just one level.enid wrote:how many levels does the iv have? and how many ivs do you have  is it just 1?

Take a look at Multivariate regression

Hiya
What is your research question  because that will point you towards the type of statistical analysis.
Are you trying to look at whether or not there are differences between different groups, which would point you more towards TTests, ANOVAs etc... or are you looking at how do each of the variables (your wellbeing measures) affect the 'amont of time spent' which would point you more towards correlational and regression tests  I'm imaginging a multivariate regression if you want to see how your 3 tests impact on your IV.
EDIT: Darn you Sarah, beating me to it

You're not calling for help, are you?!

Re: research analysis confusion. PLEASE HELP!
Thank you Gilly and Sarah, I have not done a multivariate analysis before.
my stats text books do not seem to go into them or they call it a GLM I think?
So I would have never come across it! Yes my research question is looking
At the effect of engaged time use on 3 wellbeing measures. I'm looking to see if time use
Is related to/predicts scores on the wellbeing measures. Effectively I'm going to see that
Increased engaged time use increases scores on the wellbeing measures (severity ofsymptoms, subjective wellbeing and social support). I would also be interested to see if there are any interactions between the DV's too.
Thank you again I really appreciate the replies.

Re: research analysis confusion. PLEASE HELP!
Sounds like I'd start with very straightforward correlations...

Put simply  GLM's or, generalized linear model's (Note: This is different from GENERAL linear model),typically refers to a set of statistical analysis whereby the outcome (DV) is not normal distributed. So for example binomial logistic regression  whereby the outcome variable is binary, or poisson regression, whereby the outcome variable is modelled as a discrete variable.
From what I can gather your DV's appear to be normally distributed, thus you would not need to use a GLM.
