Answer:
1. IV: Time the Bell is rang DV: Time it takes to learn the task
2. IV: Nitrogen fertilizers DV: Diversity of fish
3. IV: Time of radiation DV: Percentage of successful germination
Explanation:
The independent variable of an experiment refers to the variable that the experimenter manipulates or changes in order to effect a measurable response in the dependent variable while the dependent variable is the variable that responds to the changes made to the independent variable.
1. In scenario 1, the TIME THE BELL RINGS is the independent variable because that is what the experimenter controls or has power to change. On the other hand, the dependent variable is the TIME IT TAKES TO LEARN THE TASK because it is the measured variable that responds to the independent variable.
2. In scenario 2, the USE OF NITROGEN FERTILIZER is the independent variable while the DIVERSITY OF FISH is the dependent variable.
3. In case 3, the TIME OF RADIATION is the independent variable while the PERCENTAGE OF SUCCESSFUL GERMINATION is the dependent variable.
