Question

a study was created to test the effects of fear in children. the hypothesis of the experimenters was that if babies were exposed to fuzzy bunnies and at the same time a loud cymbal was struck close behind them, then that child would be afraid of all fuzzy things. another group of children would be exposed to bunnies without any loud noises. the study was carried out as planned and as a result, hundreds of young children developed fear of all cute furry bunnies rabbits.

Explanation:

In an experiment, the independent variable is what is manipulated, the dependent variable is the outcome measured. Here, the cymbal (loud noise) presence/absence (manipulated) → independent variable. Fear response (measured) → dependent variable. Experimental group (cymbal - Group 2) vs control (no cymbal - Group 1).

Answer:

Independent Variable: Cymbal (loud noise presence/absence)
Dependent Variable: Fear (of fuzzy bunnies)
Experimental Group: Cymbal Group (Group 2)
Control Group: Quiet Group (Group 1)
