I found out about these forums from another website they said I may be able to get some quick help here.
Quick background - I own my own business and wanting to do some statistical analysis on the effectiveness of our advertising spend on bringing in new clients to my business. I am in the medical field and did statistics and research methods at university, but this was a long time ago and I am confused reading through my old text books.
I simply want to correlate our advertising spend per month to our new clients per month and see if our increased advertising spends during certain months or quarters correlates to more new clients. I have all the data for several years with new clients for the month and exactly how much was spent on advertising for each month.
Can someone give me some help to figure this out?? Any help would be much appreciated.
