More specifically, reliability is concerned about the general consistency, while validity emphasizes the accuracy of a given measure (Cohen et al., 2017). An applied research’s validity is regarded as the extent to which...
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...
The cooling curves of the pure compounds and various mixtures were used to construct a solid-liquid phase diagram of the biphenyl and naphthalene systems. A phase diagram shows melting, freezing, vaporization, and sublimation. These graphs represent the temperature, pressure, and composition relationships. One of the easiest ways is to use...
Statistics are an important tool for researchers and policymakers when analyzing particular social-related issues. The types of statistics that can be accumulated in relation to the area can be either objective or subjective (Rahman, 2020). Objective statistics are grounded in physical realities and numbers. Subjective statistics are typically related to...
The 1961 Milgram experiment can be considered a non-experimental design. It is essential to first differentiate between an experimental and non-experimental research designs. In the former, a controlled factor is subjected to some type of treatment and then compared with another factor that was kept constant. It also entails allocating...
The articles by Hynek and Condon are both dedicated to the topic of UFOs and their public perception. Despite the ten-year gap between the publications of both pieces, the general idea of the authors is the same – subjective experiences ought to be considered with caution. However, the implications of...
Introduction Crude acid phosphatase, an enzyme, is vital in speeding up biological reactions, and as such, it comes in handy in the manufacture of proteins as well as the conversion of sugar compounds into usable sugar substrates. The enzyme phosphatase is an ubiquitous acid found in both plants and animal....
Introduction The aim of the experiment was to validate Kirchhoff’s Rules as applied in electrical circuits. The practical work was undertaken virtually by using the PhET interactive simulation (PHET Interactive Simulations, 2021). The setup was designed and arranged as shown in the figure below. The lab work employed the general...
It goes without saying that medical researches deserve close attention and consideration. The medical researches which are made with the claim of their further applicability deserve far more consideration and interpretation, lots of preliminary work before the actual living out of the claims, found within a research book. There are...
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...
In the recent past, NASA has spearheaded efforts to understand the planet Mars through its Mars rover referred to as Curiosity that gathers evidence to show whether life is possible there. The sole idea is to colonize Mars, an idea that some scientists believe is possible and must happen. Mars...
Continental plates are constantly moving which leads to a series of natural occurrences. One of these occurrences is the earthquake, which results from sudden contractions along the fault lines. Therefore, these sudden contractions transfer from their epicenter in form of seismic waves. According to Brûlé et al. (2017), there are...
Modern data analysis includes multiple approaches allowing to conduct of tests for dependent and independent variables in different scenarios. Descriptive statistics, correlation, T-test, ANOVA, and regression can be applied to test healthcare researches information to provide exact responses to studied questions. For example, the answer to “What is the average...
Peer-reviewed articles are primarily based on academic studies, precisely research that has been conducted. They exhibit properly defined methods and attitudes of scholars. When reading through the article, the sense and taste of intelligence are experienced that obviously attracts an arousing strong curiosity. For an article to be called peer-reviewed,...
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...
Research design is very critical in determining the validity, reliability, and generalizability of the findings. For the research findings to be credible, they must pass statistical tests of validity, reliability, and generalizability. Since positivists support the use of empirical evidences in the criminal justice system, they apply statistical tests quantitatively...
Introduction Sedwick, Lance-Smith, Reeder, and Nardi’s (2012) main apprehension was the increasing rate of Ventilator-Associated Pneumonia (VAP) in critical care patients. Ventilator-associated pneumonia is currently becoming one of the common complications among the Healthcare-Associated Infections (HAI) not only within the United States but also around the world. Therefore, VAP is...
Introduction Statistics has been applied in major attributes of human life Thus it has been deemed of paramount significance for students especially in major areas that impact on human existence to have a strong statistical and analytic background. The essay thus is a close statistical examination of education based on...
Introduction The four lenses of liberal arts are used to examine topics from different points of view. They allow one to understand not only what a topic entails, but how its came into existence and why different opinions of it can form. They also help one to form a more...
Introduction Both the Atomic Force Microscopy (AFM) and the Hall Effect represent unique methods of magnetic field measurements. While the AFM method employs a probe that is placed on its tip to take these measurements, Hall Effect explores ‘Hall’ voltage to achieve the same. These measurements come in handy in...
New Mars rover “Curiosity” landed Mars on August 6. According to the comments of its creators, the purpose of this sophisticated device is in participating in long term robotic exploration of Mars (Webster par. 2). In particular, the mission of this Mars rover is to attempt answering the question that...
Biostatisticians use a multiplicity of statistical terms and concepts that help them to organize numerical information in various formats, understand statistical techniques, and make informed decisions. These terms are important in helping professionals to not only design, analyze and interpret data of studies in public health and medicine, but also...
Introduction Research is a French word that means to seek closely and is well expressed by the word “recherché”. It was meant to inquire about a particular topic to learn more or to dig the root cause of a problem or a particular situation. In other cases, the word researching...
This article under research studies the aging data in Japan across all generations and genders. It also looks at how the social-economic structure of Japan and how it has played a role in this factor. In order to carry out an efficient and accurate analysis of this topic, statistics were...
