Discussion: Categorical Data Analysis

As with the previous week’s Discussion, this Discussion assists in solidifying your understanding of statistical testing by engaging in some data analysis. This week you will once again work with a real, secondary dataset to construct a research question, perform categorical data analysis that answers the question, and interpret the results.

Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will post your response to the hypothesis test, along with the results. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another.

To prepare for this Discussion:

· Review Chapters 10 and 11 of the Frankfort-Nachmias & Leon-Guerrero course text and the media program found in this week’s Learning Resources related to bivariate categorical tests.

· Create a research question using the General Social Survey dataset that can be answered using categorical analysis.

By Day 3

Use SPSS to answer the research question. Post your response to the following:

1. Include the General Social Survey Dataset’s mean of Age to verify the dataset you used.

2. What is your research question?

3. What is the null hypothesis for your question?

4. What research design would align with this question?

5. What dependent variable was used and how is it measured?

6. What independent variable is used and how is it measured?

7. If you found significance, what is the strength of the effect?

8. Explain your results for a lay audience and further explain what the answer is to your research question.

Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

By Day 5

Respond to at least one of your colleagues’ posts and comment on the following:

1. Do you think the variables are appropriately used? Why or why not?

2. Does the analysis answer the research question? Be sure and provide constructive and helpful comments for possible improvement.

3. As a lay reader, were you able to understand the results and their implications? Why or why not?

Part 1

It is possible to determine the connection between two variables using regression analysis. Using this method, you may determine how much of an effect the independent variable has on the dependent one (Wagner, 2020). The greatest applications for regression analysis are thus those that include a large number of variables that can be evaluated independently. The major goal of the regression model below was to investigate the link between job status and internet and mobile phone use. According to the data in table 1, this model can account for just 4.2% of the total variance observed. A statistically significant model can be found despite the model's low significance score. ANOVA table 2 is also statistically significant, meaning that there is a statistically significant difference in the mean values of the variables.

Research Question

Is there any impact of cell phone usage and internet usage on employment status?

These crucial coefficients may be found in the following table (see row three). The beta readings indicate that the constant is 0.057. Cell phone usage is represented by a score of 0.134, while internet usage is represented by a score of 0.130. Statistically, each of these beta values is significant.

The model is given as:

Employment Status = 0.057 + 0.134 cell phone + 0.13 Internet usage.

Part 2

Research Question

Does the sampling unit has an impact on the employment status?

There are now three dummy variables created from the sample unit variable, one for each kind of location: urban, rural and semi-urban.

Phase 1

The major goal of this model was to examine the link between the location of the sample units (urban vs. rural) and the participants' job status. This model accounts for 1.1 percent of the variance in the data, according to R square findings. Despite the fact that the result is statistically significant, the value is quite low.

The table of regression coefficients may be found in the preceding section, in table 6. In this instance, the Beta values derived from the study are shown. These findings lead us to believe that the beta is always going to be 0.227. A positive beta value was found in the rural and urban regions. However, only the urban factor was shown to be statistically significant. Hence, the model can be given as below:

Employment status = 0.227 + 0.035 rural + 0.17 Urban

Phase 2

Using regression analysis, a new set of dummy variables was tested in the second phase. Detailed results are shown in Tables 8,9, and 10. In the second model, the urban and semi-urban sample units were the primary focus of attention. Only 1.1 percent of the model's volatility can be explained by this data, according to the model summary. The model's significance is also backed up by the data.

There is a breakdown of the regression model's coefficients in the following table 9. The constant beta was determined to be 0.296 in the table. To put it another way: The Beta values for the urban variables were 0.01 and for the semi-urban variables 0.023. Semi-urban was not statistically significant in the model used in this study. The regression equation is given below:

Employment status = 0.296 + 0.1 urban – 0.023 semi-urban.

Implications for Social Change

In order to affect societal change, the data presented above is crucially important. It goes into great depth on how the dependent and independent variables are connected. Part two involves assessing the impact of different sample units on an individual's employment status. Regression analysis aids in finding the link between variables that are crucial to creating social changes in the environment.
