What statistical test would best suit my data?

[confusedmedicalstudent]

I have done a project looking into whether the removal of a financial incentive from a health provider showed any statistically significant change over a period of time to the attainment of a specific health outcome. I have the data values from when the incentive was in place and then after it was removed. I am wondering what statistical test would be most suited in determining if there is any statistically significant change

Hi CMS

What outcome do you want to check?
I assume you compare period before removing the incentive, to period after? What timeframe do you check?

If you want to compare the average of the outcome before, to the average of the outcome after, the default test is paired T-test.
