**Anova for repeated measures, mixed effects regression or survival **
I have an RCT where I compare 2x 40 slopes (20 different skills learned over time by 80 subjects):
- Condition one (n=40) is learning skills assisted by a smartphone.
- Condition two, control group (n=40) : non-smartphone assisted learning. I have daily entries over a year (360 measuring points), and I'd like to be able to show difference between two groups.
I'll be comparing Days used pr. learned skill (it will probably take 10-30 days to learn, each skill, more skills can be learned at the same time) I have cluster randomized at 4 different sites. Not all will learn all 20 skills in the 1 yr. timeframe.
I'm uncertain as to what statistic to use here? Survival with each learned skill as an "event" (will help me by the possibility to censor) linear Mixed effects: Slope (days needed pr. skill)~time + smartphone condition + error Maybe anova for repeated measures
Any suggestions as to what would give me best use of my data. Best picture of differing p values? My research question is does smartphone-registration enhance learning of skills ?
Im no stats wizard, so all input about these or other procedures are very welcome Kindly Stig
