Question

Dr. Kline is an environmental psychologist who wants to know whether visiting zoos causes people to have a more positive attitude toward environmental conservation. He polls a group of 45 people attending the zoo on a Saturday morning and finds that 69% of them report having a positive attitude toward environmental conservation after their visit. Which of the following is true?

A. He can make a strong causal claim about the effect of zoo visits on environmental attitudes.
B. His study does not qualify as an experiment.
C. He does not have a dependent variable.
D. His control group is people who did not visit the zoo.

Answer 1

B). His study does not qualify as an experiment.

Step-by-step explanation:

Dr. Kline's study would not qualify as an experiment because it does not involve an experimental group in order to compare the results with the control group. In order to ensure that the results are not merely a chance but there is a causal relationship between the change in the independent variable and its effect received by the dependent variable. This also makes the conclusion reliable but in the given case, DR. KIine simply questions a group of people already visiting the zoo without having an experimental group with some modulations. Hence, option B is the correct answer.
