We've tabulated the scores for the third round of the "weather forecasting contest." The third round was won by the Weather Network, followed by AccuWeather, then Environment Canada, and Weather Farm.
The contest consists of grabbing their forecasts at the same time on one day, for the following three days, for Saskatoon, SK. We then check the Environment Canada posted results after the three days have passed and calculate the results. Weather Farm's forecast is actually for a site north west of Saskatoon, so we post their results in comparison to their site's actual weather results and those of Environment Canada's.
Here is the formula we used.
We enter their forecasts into the below sheet and do the calculations. Here are the current results:
