Constants, Control, and Experimental Groups Practice 1

A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored. What is the control group?

• The group placed in the quiet room

• The group in the room where they played jazz

• Jazz

• Sleep time

• Room Temperature

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 bunny rabbits. What is the independent variable?

• Babies that heard a loud cymbal every time they saw a bunny

• Fear

• Cymbal Sound

• Age

• Babies that did not hear a loud cymbal every time they saw a bunny
