Question

Anton and his friends are discussing a study he read about in his developmental psychology class. In the study, the researcher made the claim that a majority of middle school students who are bullied have low self-esteem. Clarissa questions the study, saying, "I am not sure that I am convinced—I am not sure you can really measure being bullied." Quinn also questions the study, saying, "Which middle school students did they study? I am curious if they included both private and public school students." Manish also is curious about the study, asking, "I wonder how strong the relationship is between bullying and self-esteem. Could you predict one from the other?" Refer to Research Study 3.3 Anton is concerned that the researcher made a Type I error. What does that mean?

Answer 1

The researcher concluded there was a relationship, but there isn't really one.

Step-by-step explanation:

We can say that the researcher made a type 1 mistake because the researcher concluded that there was a relationship, but it doesn't really exist. This premise defended by the researcher shows a false positive, where he assumed that the theses he made to approve the hypotheses of his study did not work, but the researcher did not realize and took the results as true. This type of error usually occurs when the test duration has not been respected and when the sample size has been set incorrectly.
