Being a fellow of the dorkhood, I’d be very interested in the data myself.
Note on that last one – it only shows 6 contests. The correlation (r) is only for the top 40 vote getters. For this sample set, the hypothesis (“Early posting garners more votes”) is likely to be false. The “p” value is a measure of the confidence in the correlation. Lower p’s mean that there is less likely to be an error. Statisticians think that a p < 0.05 is a good value (if I recall my stats classes correctly).
