Final answer:
The correct setup for Jimmy's study involves keeping all sleep-affecting factors constant, a control group not exposed to jazz, an independent variable of jazz music, a dependent variable of sleep duration, and a hypothesis on how jazz music affects sleep duration.
Step-by-step explanation:
Jimmy wishes to study the effects of jazz on people's sleep patterns. In designing this experiment, specific components need to be defined correctly:
- Constants are aspects that do not change throughout the experiment.
- Control Group does not receive the experimental treatment.
- The Independent Variable is what the researcher changes or controls. In this case, it's whether jazz music is played or not.
- The Dependent Variable is what the researcher measures and expects to change. Here, it's the sleep duration.
- Hypothesis is a statement about what the researcher believes will happen between the independent and dependent variables.
The correct setup for Jimmy's study should ensure that all factors affecting sleep are held constant except for the presence of jazz music. The correct answer would be: Constants: All other factors affecting sleep (such as light, noise, and room temperature); Control Group: Group without jazz music; Independent Variable: Jazz music; Dependent Variable: Sleep duration; Hypothesis: Listening to jazz music will either increase or decrease sleep duration based on the experiment's findings.
