I've been doing some analysis projects at work and I've been supplied with some dummy data regarding whether an applicant has applied on a weekday or weekend (I have set this as 0 for weekend and 1 for weekday. The other variable I have is the total time it took for an applicant to apply and get recruited.
Now from a statistical stand-point if I use a regression analysis against this dummy data and I receive a P value < 0.05 - can I say safely say that there exists a linear regression relationship and that the day the individual applies has an impact on overall recruitment? Of course the upper and lower ranges are also +ve as well as an adjusted R squared of 0.70.
To verify the relevance of this variable I was thinking of using a multiple regression analysis to test for the P-values and see whether there is an associated increase with any other variables (to test for mutlicollinearity).
