| Q: | Which of the following reinforcement schedule is used in a classroom where students are provided grades for each assignment that is submitted? |
| A | fixed-ratio | |
| B | variable-ratito | |
| C | fixed-interval | |
| D | variable-interval |
The correct answer is A. This question can be solved with logic alone. Since students get a grade for each assignment, there is a 1:1 ratio. Thus, the ratio is not variable and is assignment-based, not time based.
