PUBH-6033/8033: Final Project Results Template

Results (1 page of narrative plus charts and SPSS syntax code)

In Week 9, you are asked to prepare the Results to your Final Project. It should include the following components:

• Description of the steps you took to conduct your statistical analyses.
• Summary of your statistical findings**
  • Narrative description
  • Tables and graphs (Be careful–too many tables and graphs decreases clarity)
• Be sure to include your SPSS codebook as well as the syntax code used in SPSS to conduct your statistical analyses. The page length of your code may vary according to the types of analyses conducted.

**Note: Do not attempt to explain your results in this section; only report your findings

Following is a template for how the Results might look for a research question that includes two categorical variables and involves Chi-square analysis.Note that when you report statistical findings in APA style, you do not cut-and-paste tables from SPSS. They must be reformatted and summarized into Word tables. Your Results should include the same components in this order but the specifics should be relevant to your dataset, research question, and variables. Be sure to refer to feedback from your Week 7 assignment to make sure you have selected the right statistical test for your study. ____________________________________________________________________________________

Results

Statistical analysis steps

Statistical analysis was conducted in SPSS version 21. First the asbestos.sav dataset was uploaded to SPSS and checked for errors. Second, descriptive statistics were run on variables relevant to this studyusing the following steps: >Analyze > Descriptive Statistics > Frequencies. Pie charts were indicated under the Charts box to visualize the data. Finally, Chi-square analysis was performed using the following steps: >Analyze > Descriptive Statistics >Crosstabs. The independent variable “asbestos” was moved to the Row box and the dependent variable “lungca” was moved to the Column box. Chi-square was clicked under the Statistics button and then OK.

Findings

The asbestos.sav dataset included 285 valid cases. One-third of cases (33.3%) had lung cancer (Figure 1) and 41.4% had been exposed to asbestos (Figure 2). Of the 118 cases that had been exposed to asbestos, 80 had lung cancer and 38 did not have lung cancer. Chi-square analysis showed that there was a statistically significant association between asbestos exposure and lung cancer, Χ² (1, N=285) = 107.631, p<.01 (Table 1).
