STATISTICS ASSIGNME NT 2 Statistical Analysis of High Temperature Weather Predictions
Part 1 Independent Variables: · Location - A - Inland, B - Coastal · Source - I - BOM, II - Weather Channel These independent variables were chosen as it is possible that the interaction of the two have a role in the accuracy of the data being collected. The Location variable refers to the location in which the data was being measured but not recorded i.e. Data collectors used weather channels to collect data online rather than physically collecting the results themselves. The Source variable refers to which weather channels or service that the data collectors used to access both the predicted and current weather conditions. Dependent Variable: · Accuracy of Max Temp This response variable was chosen as it is a simple way in which the accuracy of weather predictions varies in each location without being overly complicated to calculate. 5 Random Replicates of Treatment Combinations rain actual for the day 4% 0 Day City Service max temp forecast min temp forecast rair forecast for the day humidity at 10am windspeed at 10am max temp actual min temp actual humidity at 4pm windspeed at 4pm Saturday Wellington BOM Saturday Melbourne BOM Saturday Hobart BOM Thursday Brisbane BOM 12 B.O Y 0.99 19.0 11.0 9.0 Y 0.93 new.location 24.0 Coastal 16 NA N NA 17.5 16.0 NA N NA 17.5 Coastal 16 8.0 N 0.5 22.0 14.0 7.0 N 0.56 19.0 Coastal 22 8.6 N 39.00 9.0 24.7 8.6 N 16.00 17.0 Coastal Monday Hobart BOM BOM x Coastal x High NA NA .
