Two, what are the implications for future analysis? So let's go down the list of the things to think about when your p-value is below 0.05, which is certainly the case here. We have 2.9 times 10 to the negative fifth. I know it's a little frustrating sometimes when you get the scientific notation, but in other words we're well below 0.05 and it really should be thought of as a threshold phenomenon. So we've got a significant result. What do we make of it? Well, one possibility obviously is that this is real and that it represents a real phenomenon which has implications for further analysis, but let's rule out the other possibilities. So the first possibility to rule out is sure it's significant, but it's not meaningful in…
