The document analyzes data from thoroughbred horse races to provide suggestions to clients. It finds that average handle peaks on Wednesdays, Fridays, and Saturdays. Handle increases steeply when purses are over $125,000 and when races are scheduled between 11am-12pm and 7-8pm. The analysis also finds the handle is maximized with 11 races per day and 4-12 runners per race. These findings inform recommendations to clients on optimizing scheduling and payouts to increase profits.

- 5. Graphical Analysis • Compared different independent variables to the dependent variable handle and generated some charts.

- 13. Anomaly Detection • In the handle graph(11th slide) , there are some spikes in the values which turnout to be weekends when high transaction handle occurs , so could not be termed as an outlier. • There is only one day(26-Oct-04) where we have no of races =15 , so that can be an outlier .
- 14. Suggestions for client(Summary) • As described in the few graphs and histograms , some of the things the client should take into account are : • 1.Wed , Fri , Sat , Sun : are the highest gross handle days in a week. • 2.Steep increase in handle when the purse is higher than 150000$. • 3.Restrict the no of races to 11/day. • 4.Average handle increases when the no of runners are in 4-12 range. • 5.Value of the handle is significantly high if the first race is in 11-12pm and the last in 7-8pm range.
