Data Analysis of City of Roseville Recyclable Materials <br />(control) routes. As for the quantities of materials collected, Table 17 below reflects <br />the weights of the quantities collected for each route. <br />Table 17 <br />Comparison of Dual Stream Bi-Weekly with Larger Bins (Thurs) vs. Bi- <br />weekly Control (Friday) <br />Total Quantities Collected by Route During Pilot <br />Thursday Friday <br />(Larger Bins) (Control) <br />September 9,150 10,825 <br />October 10,600 8,075 <br />Mean 9,875 9,450 <br />Standard Deviation 1,025 1,945 <br />o orison o e l rea Collection et o <br />eore a ri t e ilot rora <br />Table 18 <br />Comparison of Bi-Weekly Dual Stream Routes <br />Before vs. Durin Pilot <br />Total Quantities <br />(Tons) Collected by July September & <br />Route (Before) October (During)z <br />Wednesday 6,000 8,800 <br />Thursday 6,800 9,875 <br />Friday 6,500 9,450 <br />Mean 6,433 9,375 <br />Standard Deviation I 404 I 541 <br />~ The weights from Tuesday's routes were excluded from the comparison because they represent <br />weekly collection, whereas the Wednesday, Thursday and Friday routes provided more <br />comparable data as they were collected bi-weekly. <br />s Average of iwo routes (Sept. and Oct.) for each day. <br />The above results appear to reflect that more recyclable materials, by weight, were <br />collected during the pilot compared to the same collection day before the pilot. Also, <br />even though residents in the control route presumably were not aware of the pilot <br />study, they did set out more recyclable materials during the pilot. <br />B1605 13-15 <br />
