Based on the sample data provided and the statistical analysis, the following regression equation has been derived Ratings = 13. 729 1. 540* bbs + 1. 281*Winter + 1. 164*Sunday +1. 593*Monday + 1. 854*Fact + 0. 910*(SQRT)Stars + 8. 413*Log (Previous Rating) 10. 206 *Log (Competition) This equation accounts for 44. 3% of the discover variation in ratings, with a standard error of 1. 97 (see Annex 3 for full details). Assumptions for this model can also be found on the same Annex. Methodology Set up the model, take away the data The sample size of 88 observations is greater than 30 and therefore sufficient to be considered representative of the entire population. Ratings was chosen as the just about appropriate dependent variable since the success of a network relie s on how many people watch their particular program/movie. An initial fivefold regression was then run with all the remaining non-transformed variables against ratings.This resulted in an set R2 value of 36%, meaning the regression equation accounts for 36% of the observed variation in ratings. The standard error was 2. 04, and the t-stats showed that every explanatory variable was statistically relevant except ABN, Month and Day (see Annex 7 ). Intuitively, some data points possibly could have a non-linear relationship and contrasting tests were performed to see what kind of relationships existed. It was concluded that several did exist an
