San Jose State University School of Social Work ScWk 242 Spring 2008 Lab Exercise #4: Correlation and Multiple Linear Regression Research Scenario 1a: Correlation You are a program manager in a large public child welfare agency located in an urban county. The programs you manage employ a total of 40 social workers who provide a variety of case management services to children and families involved in the child welfare system. As a program manager you are particularly interested in reducing employee turnover by preventing employee stress and burnout. You suspect that number of clients on caseload is related to employee stress levels. You ask your employees (N=40), to complete an employee stress survey that measures employee stress levels on a continuous scale with 0 = No stress, and 30 = High stress. The survey also asks employees to indicate the types of stress-reducing activities they regularly engage in, including such things as exercise. In addition the survey also contains demographic questions including race/ethnicity, age and gender. 1

Step 1: Creating the Variables 1) Directions for creating the number of clients on caseload variable: In the “Name” field, type in the variable name: clients.caseload Use the tab button or the mouse to move the cursor to the “Label” field. In the “Label” field, type: Number of clients on caseload Leave the measurement level in the “Measures” field as scale. 2) Directions for creating the employee stress level variable In the “Name” field, type in the variable name: stress.level Use the tab button or the mouse to move the cursor to the “Label” field. In the “Label” field, type: Employee stress level Leave the measurement level in the “Measures” field as scale. 2 You will need a participant ID and 2 variables for this exercise: 1) Number of clients on caseload 2) Employee stress level
Step 2: Entering the Data Click on “Data View” and enter the following data Participant ID Number of clients on caseload Employee stress level 1 50 19 2 54 24 3 60 26 4 45 15 5 42 19 6 61 25 7 65 24 8 63 27 9 43 17 10 52 20 11 51 16 12 49 14 13 67 26 14 39 16 15 42 15 16 64 24 17 54 20 18 51 19 19 60 27 20 46 15 21 42 18 22 49 17 23 66 25 24 53 21 25 65 27 26 54 20 27 58 22 28 48 17 29 54 19 30 68 24 31 67 27 32 41 21 33 59 22 34 65 24 35 41 19 36 50 17 37 60 20 38 65 23 3

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
