As part of a disability services research project, an MPH student is analyzing data from a special survey conducted in Missouri. This survey was adapted from the Behavioral Risk Factor Surveillance System (BRFSS). The survey was a random digit dial telephone survey conducted in six Missouri counties between 2010 and 2012. The sample consisted of 3,343 adults: 1,380 from rural and 1,963 from nonrural areas. The survey collected information on residential information and the presence of a disability. Disability was defined as “activities are limited in any way because of an impairment or health problem.” The student hypothesized that disability would be increased in rural areas.
a. What kind of study is this and why? (1 pt)
b. The table below shows the crude results of the study. Is there an increased prevalence of disability in rural areas compared to urban areas?
Prevalence of Disability by Urban/Rural Residence
Limited/Disability?
| Residence | Yes | No |
| Rural | 344 | 1036 |
| Urban | 444 | 1519 |
c. What are the main concerns to make the causal inference based on the data from this study?
Answer :
a)Firstly I am inadequate with regards to clarity in this question.Still,my answer would be that the examination is an example based social study including quantitative analysis.
Because 1)the research is testing into a social or medical problem,
2)it is an example study utilizing which we will make inferences for the entire population.
c)As the inquiry expresses that "the understudy conjectured that inability would be expanded in country regions' the equivalent is the principle worry of the study.whether the proposed theory is correct or wrong,
i.e whether the handicap is more on provincial territories or not.In request to demonstrate this,you can utilize the example and draw deductions accordingly.the information here can be two-way arranged dependent on rustic or non country and impaired or not as appeared in the figure given below :
| area | Disabled | Not Disabled |
| Rural | - | - |
| Urban | - | - |
You can do a chi-square test for related to see if there is a relationship between the quantity of crippled with the sort of spot they are living(rural/urban) .
Another investigation that you can do here is the time arrangement examination and concentrate the patterns in the information.
Note : As per HomeworkLib rules i have answered the questions but i have a little bit doubt in question b so i didn't answer for that question.Thank you.
