Describe the bathymetry of the ocean seafloor and how the features relate to plate tectonics The geology of the earth’s surface has been shaped by two important processes: plate tectonics and continental drifting. Continental drifting is a concept that explains how the Earth’s continents move relative to each other. The...
Introduction The film, Interstellar, presents a view of a new planet that might be habitable to human beings. This reflective treatise attempts to review the aspects of this planet that may sustain human life. Specifically, the paper examines its atmosphere, size, age, and distance to the sun. The essay also...
One of the distinctive features of the naturalistic inquiry is its focus on the context (Patton, 2014). This type of qualitative research is often associated with working in the field. Clearly, context is the key component of the research. Therefore, the theme that is the most persistent when considering the...
A statistical model can be used to reflect a particular sample of data. However, the process is not straightforward. It requires some procedures and analysis before arriving at the final true reflection of a given sample of data (Rosner, 2010). When a particular model is chosen for use in statistical...
Introduction In research work, scholars more often than note collect more than two sets of variables. In situations where two variables are collected and used for analysis, this has been termed as bivariate analysis. Typically the aim of doing this is to establish causes or relationships between the variables (Pallant,...
How can a warehouse add value to the goods in storage? Among the key tools that allow adding value to goods, improvement of the organization’s logistics-related processes should be looked into as a means of addressing the case in point. Indeed, a closer look at the subject matter will show...
Action research is a type of research used in social sciences that implies taking action toward solving problems while conducting the research. Action research has been proved to be an effective method of addressing certain issues that involve human interaction and cooperation (Stringer, 2013). Also, there are many other areas...
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 With the advancement of science, researchers must learn how to effectively create and evaluate experiments to obtain meaningful and precise deductions. One of the main contributors to such analysis is the usage of directional significance tests, which offer a way to determine the magnitude of the influence of two...
Description of the Discovery In my opinion, the most significant discovery in physics in the last century is the experimental confirmation of the existence of the Higgs boson. Announced on July 4, 2012, by scientists at CERN, this discovery is a monumental step in our understanding of the fundamental structure...
Abstract Using statistical analysis to create scientifically sound and data-driven results and conclusions is a sound academic practice that minimizes bias and unwanted bias. Conducting statistical analyses is always a tool for researching social science survey data to explore patterns and trends in specific communities further. Pew Research Center should...
The Most Important Thermodynamics Law There are four laws of thermodynamics in physics, each describing unique aspects of heat transfer. The laws include the postulation of the principle of thermodynamic equilibrium, the law of conservation of energy, heat conversion, and zero temperature. However, in my opinion, one of the most...
Introduction The practical value of statistical analysis lies in the ability to make data-driven decisions that reduce the effects of bias and subjectivity of conclusions. In this paper, statistical analysis is used to analyze differences in child mortality data between two regions. Since the data do not fulfill the criteria...
Fact vs. Theory vs. Hypothesis vs. Law Facts, theories, hypotheses, and scientific laws are fundamental elements in science. For example, something that has been consistently validated and is generally accepted as accurate is referred to as a fact (Thomas, 2021). Facts are based on empirical data and are perceived as...
What is a Double-Blind Test? Blind tests are a helpful tool in research practice. A double-blind test is a randomized trial in which neither the researchers nor the subjects are fully informed about who is receiving the intervention and which intervention (Practical Psychology, 2022). This type of study increases the...
Introduction Using statistical analysis to work with data is an essential part of obtaining results and conclusions based on facts. For the purposes of this paper, statistical tools are used to perform regression analysis, the purpose of which is to determine the nature of the relationship between quantitative variables. The...
Step 1 Scientists apply three traditional study designs, namely experiment, quasi-experiment, and non-experimental study. Random assignment and control groups are the distinctive framework elements and tools that distinguish the first category from the others. According to Rogers and Reverz (2019), it is a procedure in which “participants are randomly placed...
In order to test a complaint about the low weight of seeds in packages, the null hypothesis should be made that there is no significant deviation from the declared weight standard of 50 pounds. Accordingly, at the chosen significance level α = 0.05, a test will be carried out in...
The ongoing COVID-19 pandemic became a challenge not only for humanity’s health but also for economies and businesses worldwide. The most significant challenge was imposed in small and medium enterprises (SME), requiring rapid adjustments and modifications in organizational structure to adapt to the situation (Klein & Todesco, 2021). Marketing research...
One of the fundamental questions that every researcher should determine is to define their research interest. This point is above even the specific definition of a research topic since it represents the whole direction in which one will develop in the future. Since this choice can affect one’s entire career,...
Methodology and data analysis are some of the most crucial processes that constitute a research paper. In the research done by Xiao and Shailer (2022, p.2) to investigate stakeholders’ perception of the factors affecting credibility of the sustainability report, methodology and data analysis were used accordingly to achieve the objective...
Abstract In this work, an experiment was conducted to establish the relationship between the range and time of flight of a cannonball as a function of its initial velocity of departure from the cannon. It was determined that the cannonball would fly farther and longer if the initial velocity was...
The use of instrumental methods of analysis enhances the laboratory capabilities of researchers and directly or indirectly measures important characteristics of substances. This takes on a special meaning when instrumental methods of analysis are used to identify an unknown substance qualitatively. The analysis is unlikely to name the unknown compound...
