Question
1. A researcher wants to determine if there is a relationship between number of classes students are enrolled in (1,2,3,4,5,etcc.) and stress level scores (measured on a multi-item Likert scale). What type of statistical test should be used? 2. A researcher is interested in learning more about the protective effects of exercise. He conducts a study where he collects information about stress levels (measured on a multi-item Likert scale) and hours of exercise completed in a week (1,2,3,4,etc.,etc.). What type of statistical test should be used? 3. A child care center wants to determine if there is a relationship between how long a child naps in minutes (20,21,22,23,24,etc.,etc) and incidents of aggression (1,2,3,4,etc.,etc). What type of statistical test should be used?4. A teen violence prevention program is providing mentorship to youth who report interpersonal violence in a relationship. Before starting the mentorship program youth are asked to complete a survey that includes a measure of dating violence (measured on a multi-item Likert scale) and they complete the measure of dating violence again after the program. Researchers want to compare pre-test and post-test scores of dating violence. What type of statistical test should be used? 5. A researcher is working on a study that examines the wellbeing of older adults. She has an interest in finding if there is a difference in life satisfaction scores (measured on a multi-item Likert scale) by ethnicity (African American, Asian, Latino, White, Other). What type of statistical test should be used? 6. A bullying prevention program is underway in the Phoenix school districts. The researchers ran multiple analyses with the base line data. The researchers want to determine if there is difference in victimization scores (measured on a multi-item Likert scale) between two groups based on bullying status (yes, have been bullied; no, have not been bullied). What type of statistical test should be used? Choices are : correlation analysis, ANOVA, dependent t-test, independent t-test, mean, chi-square
