Since the hand is a necessary appendage that humans use to perform functions and coordinate activities, its assessment provides critical information regarding motor dexterity (Andersen, &...
Introduction In modern conditions, mathematics is the language of science and technology. With its help, many processes and phenomena occurring in the world, society, and nature are modeled, studied, and predicted, therefore the mathematical training of students is a necessary condition for accelerating technological progress. The scientific, economic, production, and...
This paper tries to highlight the benefits that are derived by studying the topic of probability. More emphasis is put on the prior probability and the Bayes theorem. The application of Bayes’ theorem in everyday’s life and in school can never be underestimated. The lesson has brought insight into different...
Introduction The class traveled west about a half-hour from Denver. The route cut through Lakewood City on US-6 W. On turning southwest on the I-70 W at West Pleasant View and heading towards Grand Junction and Jefferson County, we knew we were almost there because the urban sprawl that is...
Introduction The crash of the Columbia and Challenger space shuttles is often construed with varied opinions and views among Americans and indeed all people of age and size. The National Aeronautics and Space Administration (NASA), which is the worldwide leader in areas that deal with space science is one of...
Research of any kind can be successful only if it is structured and carried out properly. The proper structure of the research includes the focused methodology and the outlined practical tools to use the theoretical framework of the research. In the methodology, sampling strategies, sample size, and statistical tests prove...
What is a Research Project? It is a particular type of academic assignment that requires studying an issue of interest to contribute to theoretical or practical knowledge. The paramount goal of the research project is to examine a topic in an in-depth manner, integrate the available evidence, and produce new...
Sample and Setting The researcher will sample nurses and congestive heart failure patients at Jackson Memorial Hospital in Miami, Florida. Nurses will be sampled from the hospital’s department of cardiology. They have to have worked in this department for at least five years. They will provide their expert opinion on...
Methods The plastic mesh fabric was placed over the mouth of the Mason jar, and the metal screw band of the latter was fastened firmly over the plastic mesh sheet. Scissors were used to cut the edges of the plastic mesh to make it perfectly match the mouth of the...
Introduction Geology is a natural science which studies soil and its composition, including rocks and minerals. It focuses strongly on the transformation of the Earth’s geology over the 4.5 billion years of its existence as it underwent a continuous change and cataclysmic events, which have formed the composition of the...
Correlation is a connection between two events; e.g., when two events occur together. It should be distinguished from causation, a situation when one of the events makes the other happen. When there is a causal relationship between two events, there is also a correlation, but the opposite is not always...
Introduction Saunders et al (2009) assert that an onion can be used to represent the research process (see Figure 1). The layers of the onion must be unwrapped before one can reach the innermost core of the onion (the data collection and data analysis). The outer layer comprises of philosophies...
TEST of Reliability Application and APPROPRIATENESS Strengths Weaknesses Internal Consistency Multiple experiments Accurate Reduce confounding effects Reduce external validity Expensive to conduct Split-half Comparative study Eliminates business Minimizes errors Low reliability Prone to confounding variables Test/retest Prospective study Consistency and variability Confirmation of findings Inaccuracy of intervals Lack of significant...
The phenomenon of the normal distribution is typically defined as the graph that displays the distribution of random variables (Tong, 2012, p. 26) and usually takes the form of a sine wave on a graph (see Fig. 1 below). When it comes to applying the concept of the normal distribution...
Introduction The nuclear industry provides the modern world with rather substantial amounts of energy. However, all processes that are involved in the production of this energy result in equal amounts of waste and are highly radioactive in general. Learning from mistakes of the past, modern science operates with an extensive...
One of the distinctive features of the naturalistic inquiry is its focus on the context (Patton, 2014). This type of qualitative research is often associated with working in the field. Clearly, context is the key component of the research. Therefore, the theme that is the most persistent when considering the...
Methodology The data of annual salaries were collected from a sample of 12 operators (N = 12) in a chemical manufacturing company. The sample of plant operators was selected randomly and annual salaries recorded. Sharpe, De Veaux, and Velleman (2015) assert that sampling of data reduces researchers’ biases in the...
Introduction This paper is aimed to investigate the issue of doing good research, including discussing its peculiarities, based on the examples of three articles under consideration. The paper will take into account three types of research designs. They are the large N, the small N, and the interpretive designs. In...
Use of Tables and Figures in Research Research is an essential aspect that enables people to make appropriate use of the available information to handle issues that affect their lives. Data collecting, recording, and analyzing are critical aspects of any research process. Data collected by researchers forms the basis for...
Introduction Creating the environment, in which consistent quality improvement becomes a possibility, is imperative for the contemporary entrepreneurship. Therefore, a detailed analysis of the current production process, including the repeatability and the reproducibility levels needs to be carried out (Liu, 2014). In the context of the identified scenario, one will...
Introduction During the year 1900, in one Greek isle of Antikythera, sponge divers stumbled upon statuettes on an ancient shipwreck (Cowen 10). Their mission unearthed the many artifacts from the ruin. The shipwreck has been dated by numerous autonomous investigations to the early eras of the 1st century BC. The...
Methodology The data of the number of defective flash drives manufactured by a small manufacturing company was obtained by counting them weekly for 30 weeks and then recorded against each week as presented in the Excel file. The Analysis Toolpak of MS Excel in performing correlation and regression analyses. According...
If there is a correlation between two variables that tends to be close to linear (that is, if one variable changes, the other also does so), this tendency can be demonstrated on a Cartesian coordinate system by drawing a straight line to which the data points converge. How scattered the...
Experiment Description Introduction Identifying the flow rates of liquid in a specific environment is a complicated task. However, the adoption of the Venturi Flow Meter contributes to acquiring rather accurate results. Purpose The purpose of the experiment is to understand the principles of flow measurement and to learn to apply...
