Numerical data, measured in quantitative terms, reveal trends and patterns over time. For, example testing a new fall-prevention program within your hospital would require you to obtain a baseline fall rate before the program and then again after implementation of the program. Statistically, you could compare rate of falls before the new program with the rate of falls after the new program.

Describe another example of quantitative research design. How do quantitative research designs improve quality of care and health outcomes?

Week 5 Independent t Test Exercises

To prepare:

Refer to the Week 5 t Test Exercises and follow the directions to perform a t test.

Download and save the Polit2SetC.sav data set. You will open the data file in SPSS.

Compare your data output against the tables presented in the Week 5 t Test Exercises SPSS Output.

Formulate an initial interpretation of the meaning or implication of your calculations.

Refer to the Week 5 ANOVA Exercises and follow the directions to perform an ANOVA using the Polit2SetA.sav data set.

Formulate an initial interpretation of the meaning or implication of your calculations.

To complete:

Complete the Part I, Part II, and Part III steps and Assignments as outlined in the Week 5 t Test Exercises page.

Complete the steps and Assignment as outlined in the Week 5 ANOVA Exercises page.

Create one document with your responses to the t test exercises and the ANOVA exercises.

Part I

The hypothesis being tested is: Women who are working will have a lower level of depression as compared to women who are not working.  

Using Polit2SetC SPSS dataset, which contains a number of mental health variables, determine if the above hypothesis is true.

Follow these steps when using SPSS:

1. Open Polit2SetC dataset. 

2. Click Analyze then click Compare Means, then Independent Sample T-test.

3. Move the Dependent Variable (CES_D Score “cesd”) in the area labelled Test Variable. 

4. Move the Independent Variable (Currently Employed “worknow”) into the area labelled Grouping Variable. The worknow variable is coded as (0= those women who do not work and 1= those women who are working).  Click on Define Groups in group 1 box type 0 and in group 2 box type 1. Click Continue.

5. Click continue and then click OK. 

Assignment: Through analysis of the data and use of the questions below write one to two paragraphs summarizing your findings from this t-test. 

1. How many women were employed versus not employed in the sample?

2. What is the total sample size?

3. What are the mean (SD) CES-D scores for each group?

4. Interpret the Levene’s statistic. (Hint: Is the assumption of homogeneity of variance met? Are equal variances assumed or not assumed?)

5. What is the value of the t-statistic, number of degrees of freedom and the p-value?

6. Does the data support the hypothesis? Why or why not? 

Part II

Hypothesis: Women who reported depression scores in wave 1 and wave 2 of the study did not have a significant difference in their level of depression.  

Using Polit2SetC SPSS dataset, determine if the above hypothesis is true.

Follow these steps when using SPSS:

1. Open Polit2SetC dataset. 

2. Click Analyze then click Compare Means, then Paired Samples T-test.

3. First click on CES-D Score (cesd) and move it into the box labelled Paired Variables (in the rectangle for Pair 1 of Variable 1 and then click on CESD Score, Wave 1 (cesdwav1) and move it into the Paired Variables box (in the rectangle next to CES-D Score, pair 1, variable 2).

4. Click continue and then click OK. 

Assignment: Through analysis of the data and use of the questions below write one to two paragraphs summarizing your findings from this t-test. 

1. What is the total sample size?

2. What are the mean (SD) CES-D scores at wave 1 and wave 2?

3. What is the mean difference between the two time periods?

4. What is the value of the t-statistic, number of degrees of freedom and the p-value(sig)?

5. Does the data support the hypothesis? Why or why not? 

Part III

Using Polit2SetC dataset, run independent groups t-tests for three outcomes. The outcome variables are CES-D Score (cesd), SF12: Physical Health Component Score, standardized (sf12phys) and SF12: Mental Health Component Score, standardized (sf12ment). 

Follow these steps when using SPSS:

1. Open Polit2SetC dataset. 

2. Click Analyze then click Compare Means, then Independent Sample T-test.

3. Move the Dependent Variables (CES_D Score “cesd”, SF12: Physical Health Component Score, standardized (sf12phys), and SF12: Mental Health Component Score, standardized (sf12ment) ) in the area labelled Test Variable. 

4. Move the Independent Variable (Educational Attainment “educatn”) into the area labelled Grouping Variable. The educatn variable is coded as (1= no high school credential and 2=diploma or GED).  Click on Define Groups in group 1 box type 1 and in group 2 box type 2. Click Continue.

5. Click continue and then click OK. 

Assignment: Create a table to present your results, use the table 6.3 in Chapter 6 as a model.  Write one or two paragraphs explaining your results.

This topic helps you develop a basic understanding of quantitative methods of inquiry. In this assignment, you will have the opportunity to use the SPSS program. SPSS makes it easy to analyze data using specific tests. This assignment will give you practice with means, medians, and modes.

General Requirements:

Use the following information to ensure successful completion of the assignment:

• Review      the Topic Material videos, A Brief Comparison of Qualitative and      Quantitative Research Methods and Quantitative vs Qualitative Research,before      undertaking this practice.
• Doctoral      learners are required to use APA style for their writing assignments. The      APA Style Guide is located in the      Student Success Center.
• This      assignment uses a rubric. Please review the rubric prior to beginning the assignment      to become familiar with the expectations for successful completion.
• You      are required to submit this assignment to LopesWrite. Please refer to the      directions in the Student Success Center.

Directions:

After you have completed the assigned readings and viewed the assigned videos, write a 500-750 word paper that addresses quantitative methods of inquiry. Use the data provided in the Topic Material, “H Cup State Inpatient Databases (SID) File Composition – Number of Discharges by Year,” and appropriate statistics to address the following:

1. Describe      the different quantitative methods of inquiry.
2. Describe      the mean, median, and mode of discharges by state in 2014.
3. Compare      the number of discharges in 2010, 2012, and 2015 in all states. Are there      significantly more discharges in 2015 versus 2010 in all states?
