¶ … childhood obesity, which is proving to be a serious concern for policymakers and health administrators in the U.S. It is estimated that the prevalence of overweight and obesity among school-going children has almost tripled over the last decade. This places the generation in question at an extremely high risk for type II diabetes, cardiovascular diseases, and other weight-related complications. My main interest lies in understanding the causes of overweight and obesity among children. I am particularly interested in determining whether there is an association between the level of familial income, and the risk of childhood obesity. The research question guiding my study is:
"How does the risk of developing childhood obesity relate to the level of familial income?"
The simple linear correlation coefficient will be used to provide answers to the research question. The linear correlation coefficient is used to show the direction and strength of an association that exists between two variables; this question lends itself effectively to this test since we are interested in determining i) whether an association indeed exists between the level of familial income and the risk of childhood obesity, ii) the direction of that relationship, and iii) the strength of that association (Lane, n.d.). There are different types of correlation tests that one could use -- linear correlation, multiple correlation, or the logistic correlation. The simple correlation test would suffice in this case because neither of our two variables is dichotomous in nature (Sukal, 2013).
Variables and their Attributes: the level of income is the independent variable for this particular study, whereas obesity is the dependent variable. For this particular study, we will define obesity as a BMI equal to or in excess of 30. BMIs between 26 and 29 will be regarded as healthy. Values for BMI can be expected to take an infinite number of values between any two measures -- between 29 and 30, for instance, we could have an infinite number of BMI values including 29.1, 29.7, 29.34, 29.896, and so on. This would make the dependent...
Key terms to be considered in this process will be those concerning a developed understanding of the purpose of the study from a health perspective. Therefore, this section should provide the study with a clear identification of those terms which will be needed for an understanding of the research subject as a whole. Health Belief Model is a theoretical model framing our study. This model, which is often referred to in the justification for public information campaigns,
team-taught student grades. This research question leads to the correlation study approach in order to effectively answer the research question and provide the appropriate relationship that is between the dependent variables used in the research question. In order to effectively answer this research question, there is need to have a large sample size that will bring out the correlation between the involved dependent variables. The data collection method that can give
motivation to learn, followed by an educated and informed research question. After the research question has been narrowed down, the researcher conceptualizes how the question may be answered feasibly, within the constraints of time and budget. Such constraints can help guide the research questions into a workable hypothesis that is testable, as well as being relevant and meaningful to healthcare stakeholders. From here, the researcher can glean a cogent
It also requires conscious effort at objective because of the inherent of the method applied. Sampling plans narrows its frame to that particular sample, this to shows the group of people who are participating in the study. It samples can be selected through probability and non-probability (Mack & Woodsong, 2005). Research design In most cases research design is used in the education sector and it takes different meaning depending with how
This would significantly increase the response rate, but I would be sure the underlying aspects of the survey were correct first. Question 8: Define a hypothetical situation in which you would use an observation form in place of a questionnaire. Discuss the elements of this situation that would make it more practical for you to use the observation form. In the case of researching the development of an entirely new class of automobiles, where people often don't
Based on behavioral screening procedures, 100 students were at behavioral risk. For the 100 students at behavioral risk, 60 also showed academic risk. (2003, p. 216). Other sub-findings were detailed in the charts of mean scores and standard deviations for Letter Naming and Nonsense Word Fluency Subtests by Student Risk Group. Reading curriculum was the differential influence in students' growth in this study by Kamp, et al. (2003). Accelerating growth
