Methodology (guide 1000) †Research Design Essay

The current study employs a descriptive-comparative design, with nutrition knowledge, lifestyles, and health behaviours being compared. The scores of the two groups ( chemical formula load and obese groups) were analyzed using the Chi-square to descend if they had a relationship with being obese. Tthe study is descriptive in temper as frequencies, means, and frequency distributions were computed to describe the smacks used in the study. Samples and Sampling aim Hong Kong residents between 18 to 40 years old is the population for this investigate study.Since the total population for the subject field is very large, due to time limitations a sample size of 60 was taken for the survey, with 30 allotted to the normal weight unit group and the rest to the obese sample. Purposive sampling method acting is adopted for this look into. The selection of employees for the experimental group was made on the tail end of their partnership in the stress management workshop. To ensure the effectiveness of the study, employees belong to all levels of management, service time, sex groups and age are selected to participate in the survey.There shall be two samples used in the study, namely, 1) normal weight group and 2) the obese group. Both groups shall be chosen using purposive sampling. Purposive sampling is a popular look for recruiting method, as the sample size does not have to be determined at the ascendant of the project. It is also an advantage for this study, as the sample size entrust be constrained by time and available resources (Mack, Woodsong, MacQueen, Guest & Namey, 2005). This study volition make use of purposive sample to select respondents.This was based on respondents get outingness to participate and being available during the achievement to complete the surveys. Informed hold need to be taken into consideration at the start of any(prenominal) research project. Consend is about participants making a reasonable excerpt to take part in the study, and, as such, their aspirations need to fit with the goals of the research (Mason, 1997). The detective will ensure that the participants were fully sensible. In addition the investigator discussed the potential try for form with their supervisor and colleagues.This will highlight to the researcher potential ambiguities in meaning, confusing sentences and missing information that are likely to invalidate the measures (Patton, 2000). Informed consent requires the awareness of the researcher that betrothal is drug-addicted on an individuals understanding of the goals of the study, and what is expected of the participant. Informed consent will ensure respect for the dignity of the participant (Mack et al. , 2005). Coercion into participation will be avoided at all costs, as the study requires that participation be voluntary (Mack et al, 2005).Thus, informed consent was to ensure the well being of participants as its priority. Additionally, participants would be made a ware that their responses would directly contribute to a sharing of knowledge on nutrition knowledge, lifestyles, and health behaviours among Hong Kong residents. In addition, respondents will be reassured that the data collected would be kept confidential. No incentives will be provided for participation in this study. Results collected from the terminal analyses will be made available to respondents on request.Procedure The respondents who are clean for participation were contacted to ask for their permission in participating in the study. They were sent formal letters or emails indicating this purpose. Calls were made to these individuals to confirm their willingness to participate in the study. This study is meant to research on nutrition knowledge, lifestyles, and health behaviours of normal weight and obese individuals in Hong Kong. The primary source of data is the responses to a questionnaire (see adjunct A).A preliminary study is done on the responses collected from 5 re spondents. The questionnaire was then altered based on their suggestions. During pilot testing, wording of virtually questions is improved to make it more understandable to the respondents. Some questions were eliminated from the questionnaire and new questions were added on the basis of the respondents comments. The process was repeated once again to arrive at the final questionnaire to be used on the sample. The data collection period occured over a period of 15 days.The research hypotheses were not divulged quite an respondents were only informed that the study aims to determine differences in nutritional knowledge, lifestyles, and health behaviours between normal weight and obese individuals, and so contribute to research on this topic. It is anticipated that respondents are less likely to guess the hypotheses, and so less likely to exhibit socially desirable responses in lay to please the investigator. Respondents were called to administer the survey via telephone.Each respo ndent was told that the completion of the survey will take about 10 minutes and they were asked to email a signed consent form if he is amenable to the terms of participation. In all cases, consent forms were printed and stored separately to consent forms, and each questionnaire booklet was place only with a respondent number. On completion of the study, respondents were thanked, and were briefly informed of the studys hypotheses. Respondents were also informed that the results of the study will be made available to them on request following submission of the final thesis.ReferencesAdamson, A.J.,Rugg-Gunn, A.J.,Butler, T.J.,& Appleton, D.R.
