A sociologist wants to investigate the question, "Is there a relationship between texting during class and grade-point-average (GPA) among high school seniors in a large district?"
Which study design is most appropriate?
Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester, obtain each student’s GPA from the appropriate admissions and records office. Compare the GPA of students who routinely text during class to the GPA of students who do not text during class.

Sociologists published a study on the link between the level of masculinity and criminal behavior in men. Using a sample of newly incarcerated men, the researcher
identified 1,179 violent events and 531 events in which violence was avoided that the men were involved in. Each of the sampled men took the Masculinity-Femininity
Scale (MFS) test to determine his level of masculinity, based on common male stereotyped traits. MFS scores ranged from 0 to 56 points, with lower scores indicating a
more masculine orientation. One goal of the research was to compare the mean MFS scores for two groups of men: those involved in violent events and those who
avoided violent events.
a. Identify the target parameter for this study. Let μ₁ = mean MFS score for the violent-event group and μ₂ = mean MFS score for the avoided-violent-event group. Choose

Which of the following interpretations is NOT valid? O a. Gender stereotypes might have affected girls' relative academic performance on math and sciences such that in a country where gender stereotypes are stronger, girls perform more poorly on math and sciences compared with boys. O b. Girls' relative academic performances on math and sciences can be attributable to gender stereotypes of the country. That is, gender stereotypes cause and determine girls' relative academic performances on math and sciences c.

- Does support for assisted suicide (“death with dignity”) vary by social class? Is this relationship dif-ferent in different nations? Small samples in three nations were asked whether it is ever justified for a per-son with an incurable disease to take his or her own life. Respondents answered in terms of a 10-point scale, on which 10 was “always justified” (the strongest support for “death with dignity”) and 1 was “never justified” (the lowest level of support). Results are reported here.arrow_forwardThe article "Display of Health Risk Behaviors on MySpace by Adolescents"+ described a study in which researchers looked at a random sample of 500 publicly accessible MySpace web profiles posted by 18-year-olds. The content of each profile was analyzed.

(a) Is the study described an observational study or an experiment? an observational study an experiment (b) Is it reasonable to generalize the stated conclusion to all 18-year-olds with a publicly accessible MySpace web profile?

- A study examined the relationship between a nurse's assessment of a patient's facial expression and his or her self-reported level of pain. Data for 89 patients are summarized below: Self-Report Facial Expression No Pain Pain No Pain 17 40 Pain 3 29 We'd like to determine if there is evidence of an association between a facial expression that reflects pain and self-report pain, because dementia patients do not always give a verbal indication that they are in pain. By using SPSS or Minitab, design the appropriate test and generate the data analyses. Relate the results of the test to the research question and conclude the findings.arrow_forwardThe personality characteristics of business leaders (e.g., CEOs) are related to the operations of the businesses that they lead (Oreg & Berson, 2018).

Suppose that a board of directors is interested in evaluating the personality of their leadership .
