The inpatients infection rates will be tracked from the entire inpatient population on all three adult units allowing it to be compared to the rates prior and post hand hygiene training.
My hypothesis is that "by providing hand hygiene training to the DCS, there will be an inverse relationship to inpatient infection rates."
If I use t test to determine the difference between post and pre hand hygiene training, how can I measure inverse relationship? Is it possible to measure inverse relationship? Do I have to do correlation analysis in this case?
