The Dean of your school has asked you to organize and present data from a one-question (one-variable) survey to determine students? satisfaction in the social work program. There are 220 students in the program: 55 of them (25 percent) were randomly selected to receive the survey. The research question was ?How satisfied are you with the social work education you are currently receiving?? 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? Are they a sample or population?

Variable Value	f	%	Cumulative %
Very Satisfied	11	20	20
Satisfied	15	27	47
Somewhat Satisfied	13	24	71
Dissatisfied	10	18	89
Very Dissatisfied	6	11	100

How many students had some level of satisfaction with their social work education? What percentage of students was satisfied at some level?

How many students had some level of dissatisfaction with their social work education? What percentage was dissatisfied at some level?

Do you believe the students were satisfied with their social work education? Why?

Bivariate Analysis - Crosstabs

Being 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? What level of measurement is this?

What analysis is used?

Deciding What Test to Use & Interpreting It

You are conducting a study of grade in school and level of total adult support. You have two variables to use: grade in school (6^th grade/7^th grade/8^th 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 Rosenberg?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? What level of measurement is the independent variable?

What is the dependent variable? What level of measurement is the dependent variable?

Based on this information, which inferential test is appropriate to test this hypothesis?

You are conducting a study of gender and college degrees. You have two variables to use: gender (Male/Female) and college degree (No College Degree/College Degree).

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 inferential test is appropriate to test this hypothesis?

You are conducting a study on nativity and substance use. 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?

dStatistical Analysis Activity...Well, Really, Activities... Each of the following activities touches on some aspect of bivariate analysis. Please review all of the recorded lectures prior to attempting these activities. Do as much as you can and bring what you have (or bring your computer with it loaded onto it) to class. We will review and complete this together in class. *********************************** Frequency Distributions & Graphs The Dean of your school has asked you to organize and present data from a one-question (one-variable) survey to determine students' satisfaction in the social work program.
