2. RECYCLING Quality in the Environment Team #26: Kate Gilland & Yue Kou

3. Objective  Design and distribute a survey to State College residents  Based on data, compare results with research findings regarding recycling rates  Pin point reasons to explain results and give advice to improve quality in the environment in State College

5. Why Recycle? Create cleaner land, air, water and a better quality of life!  Saves energy  Prevents pollution  Creates Jobs  Saves money  Preserves natural resources

6. Prospective Study  The survey gives two options per question to clearly differentiate between data  The last question is more for the use of improving quality in the environment, not for analytical purposes

7. Data Collection Plan  The data is focused on students, to check whether State College meets the national average recycle rate.  The data is collected randomly twice per month for 4 months from August to December.  The following on campus halls and off campus apartments were picked as the samples:  On-campus halls: North Halls, South Halls, East Halls, and West Halls  Off-campus apartments: Lion’s Gate, Nittany Crossing, State College Park, The Pointe, Parkway Plaza, and Vairo Village.
