Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music. Which component is missing from Carmen’s experiment?
a)
a question
b)
a hypothesis
c)
a control group
d)
a description of the experiment
10.

controversial and cause debate
d)
in line with all previous historical ideas
11.
Which statement best expresses a basic scientific assumption?
a)
Interpretation of experimental results has provided explanations for all natural phenomena.
b)
If a conclusion is valid, similar investigations by other scientists should result in the same conclusion.
c)
For any conclusion to be valid, the design of the experiment requires that only two groups be compared.
d)
After a scientist formulates a conclusion based on an experiment, no further investigation is necessary.
