The methods of performing data collection in both qualitative and quantitative research are similar, but the nature of the data is different. In this view, the validity and reliability of data are...
This work aims to study the properties of active components of toothpaste. The hypothesis is that the toothpaste should have a pronounced cleansing, anti-inflammatory, and hemostatic effect on the mouth’s hard and soft tissues, but significant changes. The color of the tooth enamel will not be revealed after one week....
Youth Risk Behaviour Survey (YRBS) is conducted and designed by the Centers for Disease Control and Prevention (CDC) to gather data on youth risk behavior. The scope of this biennial study encompasses sexual activity, drug use, smoking, drinking, violence, and mental health. CDC established the YRBS system that monitors those...
Introduction Research involving human subjects is associated with various ethical concerns, hence there is the need for a regulatory body to approve clinical studies before they are conducted. Institutional Review Board (IRB) is an “administrative body established to protect the rights and welfare of human research subjects recruited to participate...
Research Design The main goal of the research brief is to set clear objectives in the form of questions and design appropriate research. The key objectives are to understand consumers’ intentions towards the category of food provided by the company and estimate market penetration in the given category of products....
An interview is a fundamental tool that is used in survey research. Also known as oral questionnaires, interviews allow scientists to cooperate directly with the subjects of their studies. Even though conducting an interview seems an easy task, this activity is more challenging than just discussing a specific topic with...
Introduction Motor dexterity is an important parameter used to evaluate the psychological state of an individual through the ability to coordinate and synchronize movements. 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 Einstein’s Theory of Relativity became a brilliant thought of the 20th century, which almost eliminated the existence of inconsistencies and contradictions of the scientific world. The theory helped to change ideas about the structure of space and time, expanding the idea of the invariability of physical laws depending on...
This paper will discuss the video Gravitational Waves: A New Era of Astronomy Begins from the World Science Festival. This video tells about one of the most significant achievements in physics in the 21st century, the first direct detection of gravitational waves. The scientists, including those who made this discovery...
Descriptive Research The first type of quantitative methods is descriptive research which aims at describing the current condition of a variable identified by the researcher. Usually, these studies are conducted to gather and systematize information about a certain phenomenon (Boeren, 2018). Prior to the beginning of the research, scientists do...
Michael Eisen, a genetics and genomics professor at the University of California, Berkeley, and a co-founder of PLOS (Public Library of Science), is promoting open access to scientific research. According to him, in reality, only scientists from the largest, well-funded universities in developed countries have full access to published researches...
Introduction Although stabbing appears to be a major crime across the world, there is no evidence that research discuses this issue exclusively. A lot of research generalizes stabbing as an assault crime (SpotCrime, 2011), and studies the effects of stabbing on victims in this respect. Different assault crimes have different...
Although existing literature demonstrates that the analysis of case study evidence is one of the least developed and most challenging facets of doing case studies, the proposed study will employ four techniques named in Yin (1994), namely pattern matching, explanation building, time-series analysis, and logic models. These analytic techniques are...
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...
The validity of research is identifying how sound a study is. In other words, research validity is evaluated by assessing the appropriateness of methods for answering the set research question. There are many aspects of valid research that should be kept in mind to make the research valid. First, sound...
Introduction Although human beings usually gain from scientific testing on animals, their distress, pain, and death do not match the likely benefits. Irrespective of animal subjects having been used in scientific research for a long time, the practice is cruel and should not continue. Researchers across the globe share their...
Introduction Research is meant to solve problems and answer questions. It incorporates creativity and systematic improvement of an idea by evidencing its workability (Gauch, 2003). Researches require proper planning and arrangement to warrant their success. Unplanned research aborts before completion or fails or provides information that is out of context....
Abstract The Abiquiu Embayment is to be found in north-central New Mexico. Through the (angular) unconformity way, both sedimentary and volcanic (rocks) superimposes pre-tertiary ones. Chicoma is the oldest form of volcanic formation. latite and andesite (flows) are its main components. It has a thickness that can measure up to...
Planets suitable for life in space are rare: few celestial bodies can simultaneously have an iron core, crust, atmosphere, and water in liquid form. However, scientists have already discovered several potentially inhabited worlds. According to González-Espada and Méndez (2016) a star that has reached a record in the number of...
Introduction Currently, the online medium, digital libraries, and printed publications provide medical professionals with abundant information related to innovative treatment methods, advancements in health care, solutions to issues in nursing, and so forth. Nevertheless, even peer-reviewed publications sometimes involve controversial findings and unverified data due to the application of irrelevant...
An earthquake is a sudden tremor of the earth’s surface or below and occurs naturally due to various factors (Cari 4). Earthquakes start either underneath or on the exterior of the earth’s crust depending on the basis that led to the tremble or tremor. The magnitude of an earthquake measures...
Characteristics of a Good Qualitative Research Credibility Credibility is an essential criterion for judging the soundness of qualitative research. This criterion entails establishing the capacity of qualitative research results to be believable from the dimension of research participants (Guba and Lincoln, 1981, p.61: Barbour, 2003, p.1019). From the perspective of...
