The algebraic laws developed by Boole are fundamentally similar to those of binary arithmetic where essential symbols are inferred...
Introduction Tectonic force are those kinds of forces that originate from beneath the surface and alter the surface configuration of the earth due to lithospheric plate movement. (Marko, 2002) Plate tectonic movement is the movement of the continental plates. It is believed that the earth was once a continuos land...
Introduction The very word research gives us an impression of authenticity. It is not based on bias or prejudices neither it’s superfluous, nor is it a simplistic argument about any problem. The research employs quantitative and qualitative methodologies as tools to achieve this end. It is used in all walks...
Culture media can be a helpful instrument in detecting and identifying the functions of various microorganisms. An ability to determine a purpose leads to a better understanding of what can be useful or harmful for the human body. This paper provides an overview of the definition, classification, and importance of...
Introduction The history of electromagnetic waves being used for communication is rather long. People have been receiving and sending signals since the end of the nineteenth century. The style of the antenna used for radio received has been the same for many years as well (Emerging Technology from the arXiv)....
Conflicting statements and arguments are the objects of research of logic as a science, and special mechanisms exist that are designed to determine connections among the individual components of various hypotheses and their veracity. One of such tools is the square of opposition that is a common technique for analyzing...
The null hypothesis is a hypothesis which states that there is “no effect, no difference, or no relationship among the variables being studied” (Smith, Gratz, & Bousquet, 2009, p. 161). Conversely, the alternative hypothesis is a hypothesis that claims that there is an effect, a relationship, or a difference between...
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...
Forecasting is a term used in economics to mean the estimation of the future state or position of a variable or a set of variables. Forecasting normally comes in handy in times of planning and making decisions for the organization about the variables in question. For instance, it could be...
Introduction This paper presents a reflection on the presentation hosted by the Space Telescope Science Institute (STScI). The event provided insight into the process that takes place between the scientific idea and Hubble press releases. The presentation allowed me to learn a lot about the phases of Hubble observation, as...
The exploration of space is one of the strategic goals humanity is likely to focus on in the nearest future. Astronauts have traveled to the Moon and have spent months during quite lasting spaceflights. It has been acknowledged that long-term space travel is associated with various adverse psychological effects (Anderson,...
Introduction and Literature Review When temperature decreases, liquid changes into solid, which is called freezing. The temperature at which the solid-liquid change takes place depends on the chemical composition of the substance (Ge & Wang, 2009b). While pure compounds melt and freeze at certain temperatures, the addition of other substances...
Introduction The discriminant analysis and the logistic regression are similar in that both these types of analysis attempt to predict the membership of a case to one of the groups into which the sample is classified by a categorical dependent variable (Warner, 2013). Both of these analyses allow for creating...
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...
Abstract The evaluation design is selected depending on the type of research question, set hypotheses, and on expected evaluative outcomes. Measurements used to gather data become determined by the chosen evaluation design. Referring to the research question, the procedures of the evaluation design, the possible access to data, and the...
People use the scientific method to address the problems affecting them. The scientific method is effective because it reduces bias and prejudice. Individuals can use the scientific method to solve their every-day problems (Trefil, 2012). This discussion highlights two scenarios that describe the use of the scientific method. The Mysterious...
Introduction There are two basic approaches to research: quantitative and qualitative. They use different data and methods; also, they can be connected to different attitudes towards knowledge and research (Polit & Beck, 2017). The present paper considers the examples of these approaches and compares and contrasts them. It demonstrates that...
Introduction The contribution made by Muslim mathematicians towards Western civilization cannot be underestimated. Unlike other religions where dogmas are not linked to science, Islam and science are correlated (Ahmed 63). Muslims have contributed greatly to the development of modern science especially in the area of algebra. Muslim mathematicians are the...
Facts in the case with respect to each of the following Engineering design The space shuttle is known to be one of the most ambitious projects of the modern age. The idea to create a space ship that would be able to fly into the outer space and return back...
Introduction Recently, there have been growing interest from astronauts on the whole issue surrounding a manned maiden trip to the planet Mars (Red Planet). Meanwhile, researchers are gathering vital information concerning the planet thanks to robots and satellites that revolve around the planet. Therefore, in order to understand what to...
A spiral galaxy is one of three types of galaxies studied and documented by Edwin Hubble. Spiral galaxies are apparently the most common in the universe and have a characteristic spiral contour; that is also the characteristic feature referred to in their name. The spiral shape is usually constituted of...
Introduction Volcanoes in Hawaii represent a special type of geological activity. They were well-known to every islander and of particular scientific interest. They are the result of geological changes that take place beneath the Hawaiian Islands and at the bottom of the Pacific Ocean. Hawaiian volcanoes also have a significant...
Research Question and Hypotheses Research question: Is the mean monthly salary of male CEOs in the United States higher than that of females? Ho (null hypothesis): The average monthly salary earned by male CEOs in the U.S. is statistically no more than the average monthly salary earned by their female...
Introduction The field of mathematics has grown tremendously over the centuries. Incorporating the theoretical and practical concepts introduced by numerous civilizations, this area of study became capable of addressing humanity’s modern needs. Both Greece and Egypt are well remembered for their significant contributions to mathematics and their extensive use of...
Introduction Every credible study requires a thorough research methodology, as it is from this process that scholars can identify, select, process, and assess the information. In research articles, the methodology section allows the reader to critically examine the report’s validity and reliability. A recent study that aims to improve firms’...
Introduction Data is a critical component of solving any problem a person may encounter. It is precious and helps make decisions on any topic, but without statistics, it will not make sense (Crash Course, 2018). Such a discipline is essential in almost every science due to the opportunities it gives....
