Null hypothesis says: SONFIRE ALMANACS LLC snow model forecast mean would not be significantly different than the actual snow occurrence mean in Ironwood Michigan.
SONFIRE ALMANACS LLC Snow Model forecast t-tail critical value had no significant difference from the actual snowfall that accumulated. This means that the SONFIRE ALMANACS LLC Snow Model forecast mean is stacked close to the actual mean. When models indicate a stacking against the mean in statistics indicates very good accuracy. The snow forecast was very accurate when looking at mean total snowfall against actual snowfall using a .05 significance level.
When running the same t-tail test against a significance level of p < 0.01 it came back no significant difference. Then I ran the t-tail test at p < 0.001 still came back as no significant difference.
The most interesting case study here is that the variance was quite a bit different at 25 with the SONFIRE ALMANACS LLC Snow Model versus 6.0356 with actual snowfall observed.
