The most manageable steps of reading a long article are to overview what the authors communicate in the papers. The reader may not get the significant meanings of what the writer speaks about in the report but develops a clue of what he is to expect. The first step is...
The study of science implies not only the presence of talent, but first of all, it requires aspiration and a strong desire. Without these characteristics, it will be complicated, and not many will be able to engage in this field. However, there are people with disabilities who could prevent them...
Introduction Statistical research is one of the most popular modes of examining patterns and variable associations. It entails collecting a large amount of numerical data and analyzing it to make meaningful conclusions. Its three most important phases are data collection, analysis, and interpretation. Often, data analysis can only occur when...
A mixed method research design is a research approach that primarily utilizes both quantitative and qualitative methods in order to cover a wide range of data assessment criteria. It is stated that it is comprised of seven main aspects, which include complexity, plan, typology, integration, timing, theory, and purpose (Schoonenboom...
Introduction In science, it is paramount to be able to analyze data in order to discover correlations between phenomena (Campbell & Stanley, 1963). This paper provides a multiple regression analysis of the data for the task 4 of the textbook by Field (2013, p. 355); the data can be found...
Introduction People have always been interested in exploring outer space and colonizing other planets. Scientists spent years developing and testing rockets that would allow humanity to reach planets where life can be better. As indicated by Worrall (2018), experts claim that the future lies in the stars and not on...
The choice of study design is a crucial stage, during which the quality of research and the accuracy of its findings are determined. Experimental and nonexperimental methods are two popular designs, which are widely used in the modern academic environment. The primary difference between them lies in the presence of...
Introduction In order to incorporate scholarly findings into practice, it is crucial to evaluate their quality at first. Academics across different areas have to possess the appropriate skills to detect bias and develop efficient strategies to minimize it. Scientific articles serve as the main channel of communication for innovative ideas...
The literature review is a fundamental part of any research, as it highlights already existing knowledge on the studied topic. Baker et al. (2015) analyzed sources related to the state of delirium and the ability of nurses to determine it. For example, Voyer et al. (2008) discuss the assessment of...
Introduction Life is a beautiful thing. However, the beauty of life is usually analyzed in a few basic physical factors without the incorporation of our basic human form. Socially, the beauty of life is analyzed from a general point of view like human relationships, love, generosity, material enjoyment, magnificent landmarks,...
In various industries, calculation and forecasting techniques are applied to identify the relevant outcomes and consequences of decisions or interventions. In particular, the two most common approaches are utilized – deterministic and probabilistic. According to Muriana and Vizzini (2017), one of the main values of deterministic models is an opportunity...
Introduction Research plans illustrate plans aimed at solving declared problems. They state the relevance of the challenges and the importance of addressing them. As such, the research plan contains the list of literature to be utilized, the methodology of the research, and the expected findings (Mitchell, 2007). The aim of...
Research is a dynamic and systematic procedure, whose aim is to establish one or more facts. Because the process is generally dynamic, there are different methods of conducting it (Houghton, Casey & Shaw 2013). The type of research strategy, approach, and technique to be employed is entirely dependent on the...
Introduction Statistics and probability have been applied in various fields. There is no doubt that statistics is a multifaceted concept with a myriad of application. (Fox 173). With this in mind, it is worth noting that there is a number of statistical analysis having varied applications and need to be...
The importance of the proposed study in the context of the existing knowledge For many centuries, nuclear reactors in the world hav been relying on fuel cycles based on uranium. Nevertheless, the element thorium is a potential source of nuclear energy in certain types of nuclear reactors. In fact, it...
Carrying out a nursing research presupposes managing a huge set of responsibilities, the safety of the research subjects being the key one. As a result, a nursing specialist in charge of a research must make sure that the study subject should not face any major threats in the process. Since...
Executive Summary The demand for electricity in today’s world is on the rise. As a result, many technologies are being tested to come up with the most appropriate one to supplement the current electric power generation. Over the years, the use of pressurized water reactors has become common. The process...
Abstract This essay gives detailed definitions of the terms paradigm, ontology, epistemology, and philosophy of science. The paper goes further to highlight the distinctions between (and among) these four terms. Researchers should be aware of these four fundamental terms. This discussion explains why such researchers should have a clear understanding...
Nursing research gained momentum within the last half of the 20th century. Currently, there is too much emphasis on evidence-based practice; hence, nursing research is imperative. Research can either be quantitative or qualitative, but critics of qualitative research associate it with epistemological issues. This paper aims at reviewing one part...
Designing an effective method for data collection is essential for without data no research can be fulfilled. Still, very few statistics textbooks pay attention to data collection methods and issues (Bauer, 2009). Therefore, it is advised that healthcare decision-makers must be well acquainted with the art and science of data...
Introductions A reasonably new hypothesis as regards the demise of the universe gives a depiction of phantom energy ripping planetary bodies in space and ultimately all fragment of matter in an unbelievable end to time. Based on science it is just about the most revolting idea ever conceived. This study...
Introduction Qualitative research is not precise and sometimes looks vague because of the extreme broadness of the area to be covered, hence the difficulty in defining it. Firestone (1987, p.17) states that qualitative research methods are established on a “post-positivistic, phenomenological world view”, with assumptions that social constructs define reality...
Contrary to popular belief, mathematics plays an essential role in human life. It should even be said that without knowledge of mathematical formulas, regularities, and concepts, we would not be able to progress and develop. People mistakenly consider that mathematics is limited to the textbook and the school board, but...
Selecting a Suitable Topic in Business Research A topic for business research is the beginning of an investigation; however, the success of the study strongly depends on the correct choice of the focus area. The topic should be potentially successful and appropriate for the specific person who intends to conduct...
Generally, t-test include five assumptions that have to be taken into consideration at all times when the analysis is executed. As discussed by Kim and Park (2019), first, the scale of measurement applied to the collected information follows an ordinal or continuous scale. Second, the data is derived from a...
Introduction Finite Elements Analysis (FEA) also known as Finite Elements Method (FEM) is an approach to solve a physical problem by solving the Governing Differential Equations by converting the Governing Differential Equations into a set of Linear Equations over smaller domains or elements known as element level equilibrium equations. These...
Abstract This report covers the exploration of system identification and parameter estimation for a first-order system. The choice of a system is justified by the use of the first-order differential equations. They are necessary to determining time constant ???? and steady-state gain ????. Throughout the experiment, static, frequency response, and...
