Environmental psychologists are interested in sustainable behaviors in public spaces. A research assistant conducted an observational study outside a major suburban supermarket to investigate whether there was a generational difference in the use of reusable bags versus single-use plastic shopping bags. The data collected is presented below.
| Frequency of shopper type using reusable vs single-use plastic bags | ||
|---|---|---|
| Reusable bags | Single-use plastic bags | |
| Younger shoppers (under 30) | 45 | 75 |
| Older shoppers (30 and over) | 82 | 38 |
