My final year project

I have to conduct surveys on the following group of people:

Primary school pupils
5 pupils each from standard 1-6.
5 x 6 = 30 pupils

Secondary school students
6 students each from form 1-5.
6 x 5 = 30 students

Uniten students
5 electrical power students, 5 electrical-electronics students, 5 civil engineering students, 5 mechanical engineering students, 5 from IT and 5 from Computer Science.
Total = 30 students

The public
10 people from low income background, 10 from middle income and 10 from high income.
Total = 30 people.

In conclusion, I have to conduct the survey on a sample of 120 people! Really hope that things will turn out well, especially for the school kids. I hope I can conduct the surveys at the schools this November before the school break. =(

My topic is on environmental education, but I myself never recycle, never bring my own shopping bag and always use the plastic bags, I waste water and electricity. How ironic.
