Research Design

 

Research design refers to the specific type of study that you will conduct. Research design is normally consistent with one’s philosophical worldview and the methodological approach the researcher chooses. In this case, you are using a quantitative methodology. As we have discussed in this course, quantitative research designs can be experimental and non-experimental. You will be using a non-experimental design that can include descriptive statistics, correlational or causal-comparative research methods.

Research methods refer to specific procedures selected based on the chosen design. This is where you will provide detail on how you collected and analyzed your data. For quantitative methodologies, research methods can be quite detailed and require that attention be paid to recruitment, sampling, sampling frame, sample size, surveys, pilot tests, observations, data collection, data analysis, statistical procedures, data interpretation, coding, validity, reliability, generalizability, reporting, etc.

For this assignment, you will develop the research design for the Sun Coast project, utilizing this  Unit III template (See attachment) to complete your assignment.  Only use peer reviewed references from Columbia Southern Library plus the above book for this course. See Literature Review essay below.  Also see other attachments.

Your Unit III research design submission should include the below elements.

• Research Methodology: Describe and justify the choice of research methodology and why it was most suitable to solve the problems. Be sure to compare and contrast this choice with the design that was not selected.
• Research Design: Explain whether the research design is exploratory, causal, or descriptive. Provide the rationale for the choice.
• Research Methods: Review the research questions and hypotheses you developed in Unit II, and then decide on the most appropriate research methods to test your hypotheses. They might include a combination of experimentation, descriptive statistics, correlation, and casual-comparative methods. Be sure to specify which method will be used to test which research question and hypotheses, and explain why that method was most appropriate.
• Data Collection Methods: Specify how the data were most likely collected to test the hypotheses. Data collection methods include, but are not limited to, survey, observation, and records analysis. Be sure to specify which data collection method was used to collect the data needed for each research question and hypothesis. Please note that one data collection method could capture the data for several research questions and hypotheses.
• Sampling Design: Briefly describe the type of sampling design that was most likely used for the data that were collected. Choices include, but are not limited to, random sample, convenience sample, etc. Explain your rationale for your sampling design selection(s).
• Data Analysis Procedures: Specify which statistical procedures will be used to test each of your hypotheses from among correlation, regression, t test, and ANOVA. Explain why each procedure was the most appropriate choice.

The title and reference pages do not count toward the page requirement for this assignment. This assignment should be no less than two pages in length, follow the 7^th addition APA-style formatting and guidelines, and use references and citations as necessary. See attachment format sample.

Literature Review

A healthy lifestyle is a key to the success of every business. Healthy lives among employees ensure that work productivity is maintained at a higher level. There is a need for every company to analyze the likely factors that may influence how healthy their workers are. Imperatively, factors influencing employee lives vary based on the kind of work and work environment (Stoewen, 2016). For instance, workers in construction and mining sites are exposed to noise, soil, and air pollution factors such as sound and particulate matter when compared to office workers. Besides, workers in the transport industry have higher life risks from accident (Loxham, 2019). Sun Coast firm works in contracts where there is exposure to more particulate matter, lead content, and particulate matter and are therefore exposed to more dangers.

Particulate Matter (PM) Article

First, particulate matter has significantly been proven to increase people’s chances for cardiovascular infections which include, bronchitis, cardiac arrhythmias as well as heart attacks, and asthma. While stressing on this, Mathew and Mark (2019) stated that smaller sized particulate matter are more dangerous relative to the larger ones considering that they are easily inhaled thus posing a direct threat to the internal organs. Generally, workers exposed to much particulate experiences high level of hospital admission, restricted activity days and absences from work (Zijlstra, 2019). The effects make the study of particulate matter by the Sun Coast firm significant as through the research, such problems can be reduced and eventually eliminated.

Sound-Level Exposure Article

Secondly, sound has changing effects on the worker. Nevertheless, sound decibel above 85 is considered dangerous to individuals, workers I particular, which in return can lead to hearing loss on the affected (Assi, 2016). For workers that are exposed to high sound daily, there’s an even higher risk for hearing loss. It is therefore important that upon studying the sound decibel in a given work environment, protective measures be put that prevent such losses from taking place (Loxham, 2019). Being that Sun Coast management has their workers exposed to the noisy environment they must conduct a study on the factors influencing sound decibels to regulate the same.

Lead Exposure Article

The third influencer at Sun Coast is the exposure to lead content. In a report by the WHO (2021), lead is described as a cumulative toxicant influencing the whole body system ranging from children to adults. Besides, Mohammed et al. (2016) stated that lead is distributed to the bones, liver, brain and kidney and is even dangerous to the fetus when the mother is exposed. Finally, there is no proven lead content that does not affect humans. So any contractor that accepts jobs working in a lead-exposing environment must find ways of minimizing the exposure to lead which justifies this study by Sun Coast.

Safety Training Effectiveness Article

Now that we know the significant impacts of lead, particulate matter, and high sound decibel on employees, companies are delighted to develop strategies for avoiding such problems. First, all the regulatory measures including masks, helmets and overalls should be provided for such employees (Wani, 2015). Besides, every new employee must be subjected to a health and safety training as part of the orientation while working in such hazardous environments. As well as existing workers being exposed to different environments of work should be subjected to mandatory safety training. Management should also place flyers throughout the work area on health and safety measures to ensure better employee health. Having tried this, it is important for the Sun Coast management to test the significance of their health and safety training efforts and if need be, change the method of training (Sorensen, 2018). As a result, the economic theory whereby healthy workers translates to high morale at work, increased specialization and in overall high level of productivity which results in high profits for the firm is achieved (Stoewen, 2016).

New Employee Training Article

The revised training program matters alongside the trainer and the training environment. With an appropriate kind of training, there is a likelihood that workplace health hazards are avoided same as the number of times an employee will ask for sick leave (Stoewen, 2016). As a result, by studying the difference in the scores of safety training between old and new training techniques, the best method can be employed that ensures the company has a forever solution to the health dangers at the place of work. As a result, the firm will be sure of high level productivity which translates to higher returns (Wani, 2015).

Return on Investment Article

The area of specialization investment is the overall return on investment. This is because demand and supply vary based on area, for instance, air, water, soil and training investments (Loxham, 2019). As such, analyzing the level of returns based on different grounds is helpful for the firm to come up with strategies for improving income from all the sectors of production.
