Design a study to show relationship between body mussiness index to asthma in both(prenominal) children and adults - Research Paper Exampleethical issues that face experimental and quasi-experimental designs and is suitable for the study that only seeks to observe body destiny index among asthma patients. intercession and control would be impossible in the study because the variables are natural phenomena. Weakness in investigating causal relationships is the designs major point of accumulation but the study is only interested in investigating a relationship and alternative quantitative methods are infeasible. Non-experimental design is also easier to implement because it is exceptional to observation variables in their natural occurrence. These justify the designs selection (The University of Southern Alabama, n.d.).The study seeks to investigate potential relationship between body mass index and asthma. It further identifies two sub groups of research participants, children, and adults. This therefore identifies three variables in the study. The first variable is incidence of asthma in a research participant and leave alone be considered as the independent variable in the study because of the limited ability environmental factors such as body mass index to determine its occurrence. The mensuration will be determined on a nominal scale, a qualitative scale that has only the identity property. The legal profession will further have two levels, existence of asthma and absence of asthma. Participants will be interviewed on previous experience of asthma symptoms and experience with the symptoms will be categorized with the symbol 1 while absence of asthma symptoms will be categorized with the symbol 2. Interviews will be used to measure the variable and its advantages ability to gather comprehensive information, flexibility, and ability to clarify interview questions and to verify responses justify its selection. Interviews also allows for collection of secondary data on a subject matter and for consideration of interviewees potentials such as intellectual capacity (Kothari, 2004).Body mass index is another variable and will be
