In public health (and dental public health), we are interested in a relationship between two variables. The scatter plot of sample data showed that there was a positive relationship between two variables. In an initial post of approximately 250 words, please address the following questions (and justify your answers):What kind of public health scenario will show this kind of relationship?How would you know if there is a causal relationship between the two variables?Would any of the analyses learned from this week be appropriate to use to test your hypotheses from Module 2? Pick a peer-reviewed article that utilized the same statistical technique that you want to use to test your hypothesis.Reference must not be more than 5 years References required: total of 2 - 1 can be textbookNo plagiarismCompetencies:3. Analyze quantitative and qualitative data using biostatistics, informatics, computer-based programming and software, as appropriate.4. Interpret results of data analysis for public health research, policy, or practice.Learning Objectives:1. Critically appraise evidence to address oral health issues for individuals and populations.2. Define hypothesis testing procedures according to variables and number of samples.3. Apply appropriate statistical tests for one, two, or more samples.4. Identify when correlation analysis and simple regression analysis should be used.5. Describe the roles biostatistics serves in the discipline of public health.

Application: O*NET Worker CharacteristicsThe O*NET content model provides information about work using six major domains. One of the six domains is worker characteristics, which are qualities that will influence how well an individual can perform job tasks and the capacity to gain the knowledge and skills to perform those job tasks effectively. This major domain provides a framework to analyze the important abilities, occupational interests, work values, and work styles (O*NET). Sometimes abilities are the most important factor to address in making an employment decision, but consider the consequences of employees working in an occupational environment that they cannot tolerate. Do you think they will produce their best work? In this Application Assignment, you focus on work styles taxonomy and scales, which are defined as personal qualities that may influence job performance. Compare the qualities of a good and bad teacher that you may have had while in school by using the work styles scales to supplement your previous analysis of the middle school teacher job. For this Application Assignment, review the media, “Employee Observation,” and your ratings of the schoolteachers in Weeks 2 and 3. Use the O*NET content model at http://www.onetcenter.org/content.htmlto rate the job in the media, and focus on the worker characteristics domain. Use the given data set from the generalized work activities in Week 3, your ability ratings from Week 3, along with your work styles ratings from this week.Reference:O*NET. (n.d).
