Introduction Regression analysis is a statistical tool that is used to develop approximate linear relationships among various variables. Regression analysis formulates an association between several variables. When coming up with the model, it is necessary to separate between dependent and independent variables. Multiple regression analysis focuses on the regression between...
Introduction Literature review is one of the most common types of academic works. This type requires applying specific search techniques. Although there are various techniques used in academic research, some general methods are applied by the majority of researchers. The main goals of this paper are to discuss the key...
Arranging information for the further analysis is an essential stage of any research, hence a variety of taxonomies for information pieces retrieved in the course of the data collection process. Therefore, the precision of the research results depends heavily on the way, in which the data is classified, as well...
Introduction The process of setting an experiment implies that every single factor affecting the dependent variable should be identified and that the crucial one should be selected carefully. In a range of scenarios, the key variable is going to be affected by not one, but two or more factors (Groebner,...
The paper in question is a dissertation chapter that dwells upon data analysis and presentation. The key challenge of the piece is to provide the major findings as well as the data analysis methodology. The introduction is rather effective as it provides some background information and reveals the subject matter...
Abstract Defining a data collection method for qualitative research is not an easy task. Because of the focus on the exploratory aspect of the study, qualitative research requires a unique model for data interpretation based on unstructured or semi-structured data analysis techniques. For the study in question, it was crucial...
Definition As a rule, the phenomenon of interpolation is referred to as the process of selecting the data that can be located within a particular range of information (Groebner, Shannon, & Fry, 2014). The identified definition can be applied to a variety of domains, including business, technology, science, education, etc....
The issue of an ancient world is probably one of the most mysterious in the history. It is amazing to think that 65 million years ago there was a different world. There were no humans but flora and fauna were diverse and beautiful. Scientists still argue on the reason of...
Introduction Also known as the gas giants, Jovian planets are the four celestial bodies that comprise the outer planets of the solar systems. These are Jupiter, Saturn, Uranus, and Neptune. The name gas planets do not imply that the planets consist of gases through a significant portion of the planet...
Introduction The generation of today must be highly responsive to attain a safe, long-lasting response to the looming waste management problem (Adamson 2012). It is normally a matter of responsibility to exercise appropriate waste disposal because some waste is highly detrimental (Adamson 2012). One of the most debatable waste products...
The process of data analysis can be recognised as one of the essential activities throughout human history. Its purpose is to collect and process different types of data to obtain new and valuable information. Data analysis is the core of academic research that drives the technological and scientific advancement of...
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...
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...
Explanation of qualitative and quantitative data Research studies require the collection, analysis and interpretation of data, which helps to infer about the population. Qualitative data are collected from study respondents in the form of a specific language that is easily understood by researchers conducting a study. Researchers use qualitative data...
The participatory action research method is one of the many methods used in qualitative research. Action research sees a lot of use in areas that have to do with people – namely psychological, sociological, and educational studies. The method is popular in these areas due to its circular nature, which...
Eliminating bias in research A crucial element of any competent research is objectivity and researchers are responsible for critically examining the methods and conclusions for bias. To help researchers avoid and eliminate biased attitude, a standard of validity and reliability may be instrumental in research (Creswell, 2013). One of the...
Introduction There are numerous sources of information that scholars and students can use in their research. They include, among others, journal articles, books, newspaper articles, and online resources. However, the bulk of these resources do not meet the validity requirements for them to be used in scholarly work. For example,...
Peer Review has got explicitly very necessary steps. It is the best process that one can refer anyone who wants his or her work to gain acceptance worldwide. There are various important things about this cycle. The researcher has to have a new idea. Research is useful for answering a...
Correlation Test To establish the nature of correlation that exists between mindfulness and two forms of happiness, namely, subjective happiness and Oxford happiness, Spearman’s correlation test was used. According to Coolican (2014), Spearman’s correlation test is suitable in the analysis of ordinal data because it is a nonparametric test, which...
Evidence of dark matter- the motion of galaxies within clusters Galaxy clusters are the leading bound formations in the cosmos. They are the best structure in which to view the impact of the dark matter. The dark matter occupies most of the space in the galaxy clusters. The dark matter...
Abstract For centuries, people across different civilizations had been terrified by the display of power that volcanic eruptions present, and they interpreted them as a sign of wrath and vengeance of gods. Clearly, with the progress of the modern science, volcanoes have been demystified; particularly, the development of the plate...
Introduction The research under analysis is aimed at the examination of the epidemiology of nosocomial infections in the framework of the Fiji region. The study was carried out by the local health care workers in the Colonial War Memorial Hospital that has the largest Intensive Care Units (ICU) adult ward...
Recent Earthquakes It is possible to provide several examples of earthquakes that took place during the past six months. For example, one can mention the Iquique earthquake that took place on 1 April, 2014. It occurred on the western coast of Chile. The estimations indicate that its magnitude was 8.2....
Introduction This study measures the Coefficient of Rolling Resistance (CRR) in a car. For this purpose, an experiment involving a car was set. A brief analysis of the CRR characteristics of a vehicle moving on a slow velocity on a flat surface is, therefore, provided. Technical Details In the course...
Though Woodbury of the present day is the exact representation of the ordinary, its geological structure may reveal the mysteries that will shed some light onto the prehistoric life on the continent and the evolution of the species, as well as the changes that North America has been undergoing since...
