How might the absence of data screening affect a researcher’s data quality, their interpretations of the data, and thereby their interpretations of their study’s findings?
A researcher is interested in ascertaining whether performance on an aptitude test is significantly related to performance on the job. He obtained an aptitude test score of 50 new employees as well as their job performance ratings from their supervisors. He, however, suspects that some of the supervisors were biased in their ratings into ranks. what statistical test should be used to test the research hypothesis? Expain your answer.
"Bullying," according to noted expert Dan Olweus, "poisons the educational environment and affects the learning of every child." Bullying and
victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of
not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure depression in a
group of bully-victims and a group of bystanders using an 18-item, 5-point depression scale. Assume scores on the depression scale are normally
distributed and that the variances of the depression scores are the same among bully-victims and bystanders.
The group of 39 bully-victims scored an average of 51.6 with a sample standard deviation of 9 on the depression scale. The group of 31 bystanders
scored an average of 45.2 with a sample standard deviation of 12 on the same scale. You do not have any presupposed assumptions about whether
bully-victims or…

Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure depression in a group of victims and a group of bully-victims using a 26-item, 3-point depression scale. Assume scores on the depression scale are normally distributed and that the variances of the depression scores are the same among victims and bully-victims. The group of 25 victims scored an average of 25.3 with a sample standard deviation of 9 on the depression scale. The group of 23 bully-victims scored an average of 20.5 with a sample standard deviation of 8 on the same scale.

- Explain two reasons why the research hypothesis is not tested directly.arrow_forwardA psychological study wants to analyze the relationship between anxiety and binge drinking; a questionnaire for anxiety and questionnaire for binge drinking is administered to each subject. What would be a good statistical test to test the hypothesis?arrow_forwardDoes quality of communication improve after people are married? Let’s consider a study by Olthoff (1989) who tested the communication quality of engaged couples three months before and again three months after marriage. In this study, 12 couples received ordinary premarital counseling. We will examine the communication quality of the husbands in this study, where higher scores indicate better communication quality.
