There are 220 students in the program: 55 of them (25 percent) were randomly selected to receive the survey. The research question was â€œHow satisfied are you with the social work education you are currently receiving?â€ Possible responses were: Satisfied; ; Satisfied; 4= Dissatisfied; Dissatisfied.At what level of measurement is the variable satisfaction?What analysis would you run for this scenario?How many students completed the survey?

Why?Bivariate Analysis – CrosstabsBeing the wonderful evidence-based practitioner that you are, you want to test whether Intervention A or Intervention B is more effective in preventing high school dropout at the school where you work. Twenty-six students participated in Intervention A and 35 participated in Intervention B. Of the 26 in Intervention A, 5 dropped out of high school and 21 graduated. For Intervention B, 12 of the students dropped out of school.What is the independent variable? What level of measurement is this?What is the dependent variable?

Why?Deciding What Test to Use & Interpreting ItYou are conducting a study of grade in school and level of total adult support. You have two variables to use: grade in school (6th grade/7th grade/8th grade) and level of total adult support (Adult support scale: high score = high support).What is the two-tailed research hypothesis?What is the one-tailed research hypothesis?What is the null hypothesis?What is the independent variable? What level of measurement is the independent variable?What is the dependent variable? What level of measurement is the dependent variable?What inferential test is appropriate to test this hypothesis?You are conducting a study to determine the relationship between self-esteem and mood. You have two variables: self-esteem (total score on Rosenbergâ€™s Self Esteem scale: higher score = higher self-esteem) and mood (total score on the Emotion & Mood scale: higher score = positive emotions & mood).What is the two-tailed research hypothesis?What is the one-tailed research hypothesis?What is the null hypothesis?What is the independent variable?

You have two variables: nativity (Born in USA/Born in Latin American country) and substance use (Total score on frequency of alcohol, tobacco, and marijuana use scale: high score = high substance use).What is the two-tailed research hypothesis?What is the one-tailed research hypothesis?What is the null hypothesis?What is the independent variable? What level of measurement is the independent variable?What is the dependent variable? What level of measurement is the dependent variable?What inferential test is appropriate to test this hypothesis?
