Compare

1) What is the difference between a hypothesis and a theory?

2) What is the difference between a independent variable and a dependent variable?

3) What is the difference between a control group and a controlled/constant variable?

Experiment• A researcher is curious to find out what effect classical

music has on people’s level of relaxation (as measured by heart rate). He suspects that listening to classical music will make people feel more calm and relaxed. He lets one group listen to classical music for one hour. He lets another group sit in a quiet room for one hour (i.e they hear no music). After one hour, he monitors the heart rate of each participant to measure their level of relaxation.– A) Independent variable?– B) Dependent variable?– C) Control Group– D) Experimental Group– E) Constant/Controlled Variables
