As a reviewer, I would start by stating that statistical significance involves a statistic’s critical value. It helps determine whether the null hypothesis needs to be rejected or fails to get rejected. On the other hand, meaningfulness implies a statistic’s efficiency and applicability to the real world (Laber & Shedden,...
Summary Today, humanity’s effect on the planet’s ecosystems is so pervasive and dynamic that it may be compared to the power of some of nature’s most formidable forces. However, the term Anthropocene, which was established around a decade ago, has only lately been widely, though informally, used in the global...
Linear regression, known for its common use in statistics, is a model showing the relationship between predictor (dependent) variable and response (independent) variable.

It is known that the universe is expanding at the present day, while its expansion rate is accelerating. As the universe consists of both dark energy and matter, they may have an influence on its expansion rate. There is a possible assumption that matter alone is enough for the universe...
In the geocentric model of the Solar System, Earth is in the center of the system, with the planets moving around it at the speed called orbital velocity. In the current heliocentric model, however, the Sun is the center of the Solar System. Apollonius, an astronomer from ancient Greece, made...
Edison, who was born in Milan, Ohio, in 1847, did not obtain a formal education to the extent that most Americans did at the time. Early on, he experienced significant hearing loss, which served as the inspiration for several of his innovations. He started working as a telegraph operator at...
Introduction The use of statistical predictive models makes it possible to predict organizational changes, including sales. Although sales dynamics for companies are a difficult variable to accurately predict, underlying trends can be determined using simple linear regression equations. This paper uses regression analysis precisely to determine the effect of square...
In order to complete a robust, valid research project, it is vital to implement a fitting methodological vision that will reflect the study’s aims and objectives. Evidently, the contemporary practice of academic research possesses numerous tools that help to address profound topics with due levels of detail and credibility. At...
Introduction There is a wide range of methodologies that can be applied to different studies. Nevertheless, one of the best options to realize the numerous factors that underlie a social issue is the utilization of phenomenology. The approach implies an attempt to deal with all the inner experiences unprobed in...
Introduction Traditionally, people believe that the exploration and study of space is exclusively the interest of adherents of rigorous sciences. Such people do not give a chance to others with a different mindset to approach this fascinating and vital topic. Space exploration has a tremendous impact on the lives of...
The Venturi effect is of particular importance in fluid dynamics, characterizing the pressure drop of a fluid as it flows through narrow spaces. The Venturi effect is named after the Italian scientist Giovanni Battista Venturi, who is also known for his work in optical physics (Gallitto et al., 2021). The...
The future of the Milky Way galaxy and the Andromeda galaxy is an interesting one since the two are projected to collide in five billion years. It is important to note that both galaxies contain a large supermassive black hole at their corresponding centers, which is the reason for the...
Null and alternative hypotheses are commonly used for testing in such applications as SPSS, which proposes different formulas for data calculation. The difference in the results over time does not always show the difference in the actual data statistics. Understanding the influencers on both types of hypotheses is important to...
Purpose The present paper aims to test several hypotheses using Pearson’s correlation analysis, simple linear regression, and multiple linear regression. All the hypotheses were tested using the Sun Coast Data Set, which included several sets of data for testing different types of hypotheses associated with employees’ health and safety issues...
Probability theory studies the objective patterns of mass random events. An event is something that may or may not happen when a certain set of conditions are met. Among the possible events, there are reliable and impossible ones. If some event happens for sure, it is called true. If some...
The Venn diagram is widely used in several branches of human activity and types of science, as it allows for an accessible and easy way to structure information for the reader. This diagram is often used when classifying any complex concepts. Therefore, it is beneficial in teaching, as it allows...
For the random sample of 100 in table 1.0, the 95% confidence interval for the mean has a Lower bound of 29527.49 and an upper bound of 45209.49. The 90% confidence interval for the mean has a lower bound of 30807.15 and an upper bound of 43929.84, as shown in...
The prior understanding of the forces of flying was based on the assumption that air is what pushes things upwards. Aerodynamics is the primary explanation behind the functions of air and flight. Exploring the topic of aerodynamics can be fun and engaging because it requires an observation of the object....
Institute of Nature Studies and Animal Behavioral Research Recycling in Nature Nature maintains balance, and its systems help in this task without waste. For this purpose, a recycling system is needed; an example is the nutrient cycle (Banerjee, 2022). Its essence is that nutrients, such as water, carbon, oxygen, and...
Introduction Frequently, employees of a company seek to know everything there is to know about their goods, facilities, systems, and so on. The research strategy is determined by the knowledge we need to gather in order to make significant decisions about a good, service, program, or other subject (Oxley, Rivkin...
The analysis of the technological hazards and health risks in Ukraine conducted by the World Health Organization (WHO) can be considered the example of the scientific method appliance. This event was researched in response to the health-related problems related to the armed conflict between Russia and Ukraine. Due to the...
Human beings have explored the universe for decades, hoping to stumble upon unique components and extraordinary elements with the potential to alter the face of the earth. However, the discovery that the human race is desperately anticipating is the revelation of life beyond earth as these answers will change societal...
Institutional Review Board (IRB) assessment aims to ensure that sufficient measures are undertaken to defend the rights and well-being of those participating as research subjects beforehand and through periodic evaluation. IRBs assess research procedures and related materials (such as informed consent forms and investigator brochures) in a group setting to...
Emission tomography, a type of nuclear imaging, is extremely sensitive and may be used to study a wide range of physiological and pathological processes. The basis for nuclear imaging is the detection of gamma rays generated by radionuclides introduced into the organism. A PET/CT scan is a combination of a...
The phenomenon of dark matter has been seen as a fascinating and mysterious issue for decades, capturing the minds of experts and ordinary readers alike. In their 2019 study, “Dark Matter Haloes and Subhaloes,” Zavala and Frenk seek to explore the changes in the velocity of dark matter particles. Since...
Sartipi, F., Palaskar, K., Ergin, A., & Rajakaruna, U. (2020). Viable construction technology for habitation on Mars: Fused deposition modelling. Journal of Construction Materials, 1(2), 1-7. Web. The research focuses on proposing the Fused Deposition Modelling (FDM) as the most practical construction process implementable on Mars during colonization. The source...
Thorium Today’s generation of industrial nuclear reactors mainly burns the U235 isotope of uranium as fuel. However, due to the multiple adverse effects of uranium fuel, researchers started searching for a more environmentally friendly alternative to generating energy and found thorium. Thorium might have elevated nuclear power production to a...
