Tutor Hunt Questions

I have a data set consisting of three variables. I am a little uncertain as to whether or not to use a linear regression analysis or multiple regression.
The question I am investigating is `To what extent variable X or variable Y predict Variable K?`
Given that the question states OR rather than AND, I would assume linear regression? I can then compare the outcomes for both variables and say which variable is a better predictor?

Any help would be greatly appreciated!

Psychology Question asked by Erin

Hi Erin, you are correct. There are two separate questions here and then a comparison required. So answer to what extent doe X predict K and then to what extent does Y predict K and then compare. Hope that helps. Ben

Because you are analysing two independent variables (x and y) then you would need to use linear regression. From my understanding you would use multiple regression when 2 correlated dependent variables are used (in this case you only have 1 dv which is k). Hope this helps, clare
