Russia is the largest country globally but remains less than two percent of the world’s population. Two landforms mainly dominate Russia; half the country is covered with lowland plains, while the rest is plateaus. The climate is mostly winter, and these features have significantly shaped the human geography and development...

Transport modes can be classified in terms of their carry purposes. In other words, transport modes are essential options for carrying passengers or freight, or a combination of both. They fall into three major transportation types, such as a land mode (that has two subcategories: road and rail), air (aviation),...

The case follows the scientific developments amongst Cumbrian sheep farmers in the aftermath of the Chernobyl radioactive disaster. When Chernobyl occurred, the area was a disaster, with everything being infected with radioactive material, including the...

Companies should be especially careful when transporting hazardous chemicals. If the mandatory conditions are not met, incidents of varying severity may occur, which will entail harmful consequences. One example of such an incident is the case. When an Italian tanker in 2000 en route from Southampton to Genoa sank with...

Output Analysis The investigator, John, was concerned about getting information concerning the data he needed for hypothesis testing to examine whether pulse rate varies among individuals who performed exercises at varying frequencies. John divided the pulse rates into three different groups and conducted a one-way between-groups ANOVA (Nowakowski, 2019). The...

Introduction Intelligent design (ID) is a theory that argues that living beings were designed by an “intelligent designer” in their current form. As a direct rebuttal to Charles Darwin’s theory of evolution through natural selection, intelligent design gained popularity in the 1990s, mainly in the United States. According to Kutschera...

Non-Parametric Procedures Non-parametric tests are choice tests if the dataset does not assume normality in its distribution (for skewed data) (Field, 2009). In addition, data that does not heed to the assumption of homogeneity of variances calls for the use of non-parametric rather than parametric tests. The preference for non-parametric...

Distinctions between Primary Secondary, and Tertiary Sources in a Secondary Search The three types of sources available in researching secondary sources are primary, secondary, and tertiary. Primary sources represent original work that is obtained by research. This work is not interpreted or subjected to the opinions of individuals. Examples of...

Introduction Today, there are three research design paradigms used in different cases depending on several factors. Some of the major factors that determine the use of certain research are expected data format and the experience of the researcher. The three design methods have different characteristics and a researcher must review...

Abstract The objective of this paper is to compare the research methods employed by two published research papers to evaluate critically the choice, justification and application of the research methods to the two articles. The paper will also identify the issues for rigor in research in respect of the topics...

The article “Grandmothering and the evolution of Homo erectus”, O’Connell et al hypothesize that Homo erectus evolved because climate changes brought about changes in their diet from meat to tubers. This change was accompanied by the need for more females to be involved in foraging and food sharing practices in...

Creswell mentioned that “researchers select the research method according to the question they pose” (Creswell, 2003, 34). It is logical to believe that in the context of research the data gathered by researchers depends on the nature of the study like quantitative, qualitative or mixed methods. In this case of...

This outcomes include cloning plants that can grow quickly, can easily adapt to harsh climatic conditions and resistant to diseases. The same...

The human body consists of cells – its smallest units made out of cell organelles. It is a tiny structure that resembles an organ with or without a membrane that predetermines its function. Comparing the cell to a factory allows one to gain a better understanding of the functions that...

Introduction Scientists have made great strides in the agriculture industry, public health, and medicine since the discovery of genetics by William Bateson in 1905. The recent field of biotechnology (the early 1970s) as a result of genetic research has led to the alteration of agricultural plants through genetic engineering. Genetic...

Abstract Qualitative research is an important choice in management research. It gives special significance to complex inter-related problems. There are many types of qualitative research. In this work, four papers are analyzed, briefly, to elicit some types of qualitative research. Introduction Creswell, 1998, defined qualitative research; as an inquiry of...

Quantitative Research Design Quantitative research can be identified as the investigation of an issue by collecting statistical data through mathematical or computational techniques. Usually, scientists outline four main types of qualitative research designs, including descriptive, quasi-experimental, experimental, and correlational (Center for Innovation in Research and Teaching). The goal of the...

Introduction Individual interviews, focus groups, and observations are some of the methods of data collection used in qualitative research. When conducting an observational study, researchers no longer rely on putting forward a hypothesis and predicting the results: instead, they observe what happens in real life. Individual interviews hinge largely on...

Differences Between Qualitative and Quantitative Methods In addition to the given information, it is necessary to note that qualitative methods enable the researchers to spot trends and phenomena. Whereas, quantitative tools serve to analyze the extent to which these trends are present at certain times and in certain populations (Mertens,...

Introduction The two major study approaches used to research in education include qualitative and quantitative research. Each approach has underlying paradigms and philosophies that determine how the study is conducted and the type of data collected. Also, each has distinct philosophical assumptions, hypotheses, methods, goals, samples, and data analysis criteria...
