Assignment -

A psychologist was interested in evaluating the effectiveness of a domestic violence prevention program in changing attitudes towards domestic violence in a sample of high school students. The psychologist recruited male and female high school students between the ages of 16 and 17 years from nine high schools in the Greater Brisbane Region. The students received a six-week domestic violence prevention program and the psychologist recorded their attitudes to domestic violence on Day 1 (baseline), Day 30, and Day 90. Based on the following data, determine whether the domestic violence prevention program had an influence on the attitudes towards domestic violence in high school students (higher scores indicate greater acceptance of domestic violence). If the ANOVA result is significant, conduct and report Bonferroni post hoc analyses to determine exactly which time points differed from one another.

Which of the following statistical analyses should be performed for this scenario? Note that you may need to select more than one analysis depending upon the specifications of the scenario.

Question 1 - Note: You may be prompted to answer all parts of this question. This does not apply to the value answer fields. Leave value answer fields blank if they are not required for the statistical test you have selected.

Question 2 - Indicate whether a one-tailed or two-tailed analysis would be most appropriate, providing a justification for your choice, and report the null and alternative hypotheses for the primary statistical analysis in words.

Question 3 - A social psychologist wanted to determine whether stereotype threat (the fear that one's performance on a task will confirm a negative stereotype about one's group) was associated with job satisfaction in a sample of mature age workers. Furthermore, the researcher wanted to determine if levels of job satisfaction could be predicted based on the level of stereotype threat. The social psychologist recruited a sample of mature age employees from the Melbourne metro region and asked them to complete self-report questionnaires of stereotype threat (higher scores indicate higher levels of stereotype threat) and job satisfaction (higher scores indicate greater job satisfaction). These questionnaire scores involve summation across multiple Likert items, so you can assume at least an interval scale of measurement for this data. Determine: (1) whether there is a negative relationship between stereotype threat and job satisfaction; and (2) if stereotype threat significantly predicts job satisfaction.
