An advantage of conducting an experiment vs. a correlational study is that:
A the cause is not related
B the researcher can manipulate the situation being studied
C experimenter effect increase the empirical evidence
D two variables are either related or they're not
I'm not sure but maybe B OR A please help me
B; A is a meaningless statement.
To determine the advantage of conducting an experiment versus a correlational study, let's review the options individually and consider the reasoning behind each one.
A) The cause is not related: This answer suggests that in an experiment, the cause is not related to the outcome. However, this is not correct. In an experiment, the researcher deliberately manipulates the independent variable to observe its effect on the dependent variable. In this way, the cause is indeed related to the outcome. Therefore, option A is not the advantage we are looking for.
B) The researcher can manipulate the situation being studied: This option correctly identifies one of the advantages of conducting an experiment. In an experiment, the researcher has control over the variables and can actively manipulate the conditions to determine the impact on the outcome. This manipulation allows for the establishment of cause-and-effect relationships in a controlled setting. Therefore, option B is a valid advantage of conducting an experiment.
C) Experimenter effect increases the empirical evidence: This option is not an accurate advantage of conducting an experiment. The experimenter effect refers to the biases or unintentional influences introduced by the researcher into the experiment, which might impact the results. While this is a potential concern that researchers must be mindful of, it does not directly increase the empirical evidence. Therefore, option C is not the advantage we are looking for.
D) Two variables are either related or they're not: This option represents a general statement about the relationship between variables, but it does not specify an advantage of conducting an experiment. While it is true that variables are either related or they're not, this idea does not capture the advantages of an experiment over a correlational study. Therefore, option D is not the correct answer.
Based on the analysis above, the correct advantage of conducting an experiment versus a correlational study is B) the researcher can manipulate the situation being studied.
