I am looking to find out the type of data I have and the ideal test to use calculate inter-rater reliability.
Research question: Functional Movement Screening: How reliable are we in our investigations?
Aim: to look into the inter-rater reliability of Physiotherapists performing a functional movement screen (12 tests) on 2 athletes.
My current data collection includes:
6 raters each scoring 12 tests with a yes and no answer.
There are 2 sets (2 athletes) in total and each rater has given me y and n data for both.
Rater 1 6 Yes / 6 No Rater 2 7 Yes / 5 No Test 1 3 yes / 3 no (from raters) Test 2 4 yes / 2 no
I would like to know:
1. the type of data I have?
2. am I looking at the reliability of the tests or do I need to focus on the raters scores?
3. the groups I need to organise the data into to give me the results?
4. the statistical test that would give me the inter-rater reliability of the raters and the tests?
I am afraid statistics isn't one of my strong points and so apologies if this is very basic but any help anyone could give me would be much appreciated as I am having difficult at present.
