  • Statistical test for two groups diverging over time?

    I have two groups (with multiple subjects per group): "Control" and "test". I measure an outcome variable for every individual repeatedly over time ("Spike per hour", specifically.) When I graph the average spikes per hour of each group over time, I see the Test group increasing in spikes while the Control group remains relatively flat.

    What statistical test is appropriate to show there is a difference between the groups?

    Thanks for any help!
