    Testing two independent variables (categorical and interval) and interactive effects on continuous data?

    Hi, I'm not sure if there is an actual statistical test for this, but I want to see how Side (Left or Right, categorical) and Depth (Interval, fixed at every 250, but I don't have data for all depths) affect a continuous parameter I have. I initially tried a multiple linear regression, I am...

    Best statistical test to encompass all my data for my research?

    @Miner Ah yes, that makes sense. That looks very promising, I will check that out now. Many thanks!!

    Best statistical test to encompass all my data for my research?

    @Miner Hi, thanks for your reply! I'm not sure if that would work, I initially tried this, but I couldn't find a way to include sex, age and depth all as independent variables. Am I missing something?

    Best statistical test to encompass all my data for my research?

    Hi, Yes, those are my predictors and the parameters are DVs. Ah ok! Sorry, regression is new to me so I wasn't aware. When we discussed this, I was told that it wouldn't be reliable as the measurements aren't technically independent as each sample has 10 slices, so there are 60 measurements...

    Best statistical test to encompass all my data for my research?

    Hi, Sorry, it wasn't clear, it's quite complex to explain, I'll provide an example table. Here's just some of the data we have. So each sample, e.g. 21 y.o male, have had parameters measured from 10 different depths. From here I want to see if the parameters e.g. BVTV, TMD etc, change with...

    Best statistical test to encompass all my data for my research?

    Hi all, I've been battling for months to work out which statistical test is the best way to make the most out of the data I have. I have been measuring depth related changes in a material. At depths of 2mm (0-2mm, 2mm-4mm etc) for 10 slices I have measured several quantitative parameters. I...
