Wegener’s hypothesis, known as the theory of continental drift, was based on a wide range of data from geological expeditions worldwide. He was intrigued by the division of the American continents and worked to explain their non-standard shape. In addition, Wegener studied animal and plant fossils on the coastlines of...
Modern economic theory, both at the micro and the macro level, ever more complex economic processes have led to the need to create and improve unique methods of study and analysis. At the same time, the use of modeling and quantitative analysis has become widespread. Based on the latter, one...
Introduction The use of scatter plot is one of the strategies that studies employ to visualize and present information to readers. Data visualization has numerous advantages, including enhancing the understanding of a phenomenon, highlighting trends and patterns, and summarizing complex information (Li, 2018). Scatterplot aids in data visualization by depicting...
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...
Introduction The paper aims to compare four ways of data collection, such as survey research, which involves a process of asking questions and analyzing responses, field research, which focuses on making observations, and secondary analysis of existing data, and triangulation, which refers to the combination of the methods. The author...
Article Critique Typically, during research, an investigator has to be physically present to collect data; this can influence the respondent’s response and behavior. The consequence of the participant’s responses is altered or biased results. Unobtrusive information collection methods may be used to resolve some of these data errors. The purpose...
The empirical rule is one of the basic statistical terms associated with the normal distribution. Also called the three-sigma rule, this law states that for a normal distribution, virtually all observable data will be within three standard deviations (Hayes, 2021). There is a ratio of 68-95-99.7, according to which 68...
The Neville Theta C function is named after Eric Harold Neville and is mathematically defined as: From the formula, K(m) is the complete elliptic integration of the first kind K’(m) =K(1-m), and is the elliptical nome (Lide 135). It should be noted that the function θp (z, m) can at times...
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...
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...
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...
The Paricutín volcano is the one of youngest on Earth and belongs to the Trans-Mexican volcanic belt. It is situated in the central part of Mexico in the state of Michoacan, 322 km from Mexico City. The eruption occurred from 1943 to 1952 in the Michoacán-Guanajuato volcanic field (Larrea et...
Introduction In the task #12.7, a two-way ANOVA was utilized to test the influence of two categorical independent variables on each of the two dependent variables: percentage of immunized persons and the number of days of immunization delay. In this paper, the claim that no statistically significant interaction was detected...
Explaining the Sample The case study titled “Social Work Research: Program Evaluation” focused on assisting low-income families. Plummer et al. (2014) mention that analyzing case studies is efficient in developing skills and expertise in social work, and this discussion is used to improve competency in sampling techniques. The program evaluation...
Introduction Aircraft building is a complicated process that requires meticulous selection of the right materials. Engineers must fully understand the qualities and limitations of all construction materials in order to make the right selection. Ideal metals for aircraft production often have minimal weight, are corrosion, fatigue, heat, and crack resistant,...
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...
Abstract and Objectives By experimenting, it was possible to address the three important objectives in this study. The first and second objectives were to determine the effects of changing the speed of the motor on the output current and voltage respectively. That was achieved by an upward and downward of...
L-alanine is “one of the 20 amino acids common in proteins” (Zhuan-Ping and Wen-Hui, 2012). It is manufactured in the muscles with lactic acid acting as its primary raw material. Consequently, it is converted to pyruvate, an important molecule in the production of sugar (glucose). L-alanine is categorized under the...
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...
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...
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...
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...
Yesterday, the author has lifted a cup to drink from it and threw a ball for the dog. In the case of the cup, they applied upward force to the cup at a constant rate until it reached the necessary height, at which point the pressure was reduced to let...
Abstract From the study, it has been found that there are many methods of bubble production. The choice of production method depends on the situation and application that the user desires. It is however not possible to recommend the best method based on the study but rather highlight the strengths...
