Week 3: Elements of Quantitative Research: Design and Sampling

Week 3: Elements of Quantitative Research: Design and Sampling 2626 unread replies.2828 replies. The focus of the Week 3 discussion is on two important elements of quantitative research studies- design and sampling. The approach or design, quantitative or qualitative, also applies to EBP projects. Both quantitative and qualitative have different designs or traditions that fall under these two broad categories. Select a single-study quantitative research study article related to your specialty track and provide the permalink to the article. Then discuss each of the following items. • Identify whether the research study design is experimental, quasiexperimental, or nonexperimental. Provide the rationale for your answer. • Identify the appropriate representation for the research study article you selected using the nomenclature of X for intervention, O for observation and data collection, and R for random a assignment to a research study group. • Identify the type of sampling (probability vs. nonprobability) that was used in the research study article you selected. • Identify one advantage and one disadvantage to the sampling type used (probability vs. nonprobability). • Identify whether there was random assignment to research study groups in the research study article you have selected. • If random assignment to groups was used, how does this strengthen the research study design? Dr. Adams and Class According to (Jagannathan et al., 2018) for dialysis patients., there are on average make up to about 30 million of the U. S. that have kidney disease. Among them 95% of them report low physical fitness levels prior to going on dialysis. The design of this topic of research study is experimental. They collected the data of dialysis patients and got the pre-information about their exercise and overall health and saw that it was high for patients that don’t exercise. They made a framework of exercise requirements to be done by a group of people who have dialysis and experimenting by giving them a plan for a work out plan for 12 weeks and trialed it to come up with their results. Within the research there is a representation that discusses the study and how it went the R) is the random study of two groups of people, group 1 and group 2. Both have 48 people in them. The X) is the intervention of the study. For group 1: There is a initial contact with exercise counseling for a lifestyle change. Bi weekly follow-ups. The workout for group one concluded was 6 minute walks and hand grips for 12 weeks. Group 2: Referral to group-based program led by certified instructor , bi weekly fallow-ups. Their encouraged to further engage in self exercises being measured by Garmin app. Then at the end of 12 weeks they would measure their hand grips and a 6 minute walk test at the end like group 1 did at the end of 12 weeks. This is the O) in the study for the observation of the study. The advantage of this would be able to see 2 groups that would fallow 1 group that did exercise and one without to see what changes happen for the good or the bad. The disadvantage would be is if one of the patients got worse with their prognosis and gave a false interpretation. Another disadvantage is if patients gave up do to being to hard and them feeling worse because they did not try. I feel that there can be a and was a random assignment given to both groups. They were informed that they were going to be a part of a study. I don’t feel that a random assignment was given because they used one as a control group that did little to no exercise verses group 2 that did a lot of exercise within the 12 weeks.
