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 A recent article titled “Avoiding Endocrine Disruptors Drops Diabetes Risk: Study” appeared on The Scientist Magazine on 27th October, 2016 (Grens, 2016). It reports the findings of an epidemiological study carried out by Transade et al. (2016). The study is titled “Population Attributable Risks and Costs of Diabetogenic Chemical...
Experimental Objectives To determine the specific gravity of different metallic objects that are denser than water To determine specific gravity of a liquid To determine the specific gravity of wood which is less dense which water is denser that it Theory By definition, density ρ0 of a substance is “a...
Benefits of using mixed methods research Many research studies adopt mixed methods approaches in their study designs that employ both quantitative and qualitative methods. Quantitative methods are concerned with collection and analysis of data (numbers) using statistical tests. On the other hand, qualitative methods are concerned with collection and analysis...
The correlation study focuses on the assumption that there is some interrelation between two variables that cannot be controlled by the researcher. In other words, the correlation is not the causation. For example, the correlation study might suggest that there is an interrelation between public health and self-esteem, but it...
Problem statement The aim of the study was to examine the relationship between nurse staffing and the observed patient outcomes in hospital settings, paying special attention to acute care, nurse staffing policies and strategies (Penoyer, 2010). In particular, the researcher notes that the relationship between low nurse-patient ratios and desired...
The interview under analysis was conducted and three participants have been involved into the study. Six questions focused on defining participants’ goals, beliefs, and ability to logical thinking. While conducting the interview, similar thematic patterns were defined among the participants. Specifically, while thinking over the most favorite historical or famous...
Throughout its history, humanity has developed numerous methods of multiplication or repeated addition. These can be more or less time-consuming and also vary in effectiveness: while some are better for education, others pursue purely practical purposes. Three such methods are traditional, Ancient Egyptian, and the method of cups and counters....
Introduction The use of methodology is very central to research in any field. In medical practice, qualitative and quantitative approaches are used in the analysis of statistical and analytical data to inform research findings. The two commonly used research methodologies are quantitative and qualitative methods, both of which have got...
Abstract The present paper critiques the sampling strategy and sample size of the selected article. Overall, it is evident that the strategies used (e.g., inclusion criteria, stratified sampling, randomization, and power analysis) were effective in maintaining internal validity and ensuring that findings could be generalized to the wider population. Introduction...
Introduction There is no doubt that statistics is a multifaceted concept with a myriad of applications; currently, everything ranging from sociology, science, business to mention but a few in one way or another incorporate statistics in their day-to-day activities. With this in mind, it is worth noting that several statistical...
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...
The Novum Organum is one of the most known philosophical works by Francis Bacon. This book was published in 1620 in Latin for the first time. With time, this work has been translated into several languages in order to spread the offered theory all over the world and provide other...
“Functions are mathematical ideas that take one or more variables and produce a variable. You can think of a function as a cook that takes one or more ingredients and cooks them up to make a dish. Depending on what you put in, you can get very different things out”....
In the mathematical sciences, much attention is paid to classification and methods of solving equations: linear, quadratic, and polynomial. There is no doubt that the practical application of the equations can be found in any environment of public life: from sociology to rocket science. Thus, the precise identification of the...
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...
Introduction Analyzing the surrounded environment it can be concluded that the law of physics are the same for both non-organic and organic world, where in living organisms these laws are under the control of biological processes. Humans as the highest forms of those organic forms are studied by a number...
Introduction Many people often learn with surprise that even without their participation in opinion polls, pollsters still release results on certain characteristics of a population that they are members. People who are ignorant about processes of doing research, often rubbish findings of research studies in which their input was not...
Isaac Newton was a famous English physicist, mathematician, astronomer, and theologian. He contributed greatly to different fields of study. But how exactly did he come up with his ideas? Newton made his discoveries with the help of mathematics, physics, and astronomy. There are also a lot of anecdotes about Newton...
Introduction The question of objectivity in the practice of science is problematic for various reasons. First, scientific theories are based on objectivity claim that they have unique access to truth. This assertion is premised on the argument that empirical science, or what is commonly known as measurable science, can validate...
Concepts of terms and terminology are critical in science and research. The term provides accuracy, clarity, and understanding of scientific thought. Terminology forms part of the specialized vocabulary, into which not common words and phrases calling subjects and concepts of various spheres of people’s professional activity included. There are specific...
People have been trying to study the level of intelligence and improve it in different species for centuries. Many types of research and studies in various subjects, such as biology, neurobiology, psychology, psychiatry, philosophy, etc., have been written over the years. It can be suggested that people are close to...
