Unsure if I have used the correct test
I studied this a while ago and am a bit rusty with remembering exactly how to get the reults I need. I basically have two sets of data and I want to see if there is any relationship to an increase in one if the other increases. Do I use a regression formula or a different test?
I have attached the data, graph and my conclusion. Please could someone have a look at it and either confirm I'm correct or shoot me down in flames and tell me I have got it totally wrong then point me in the right direction. I used the data analysis in excel rather than working the equations out myself.
Any help is greatly appreciated.
