To attain this, a description of the contexts when mixed methods researches are appropriate during a dissertation process is discussed. The ultimate goal is to justify when it is appropriate to use qualitative and quantitative research approaches. Additionally, the...
The life of all organisms is explained using the evolution theory, which identifies four forces that are responsible for the survival or extinction of organisms. However, it is important to understand the common terms used in the theory of evolution, among them species and population. Species is the term used...
Non-parametric procedures Reasons for non-parametric tests There are several reasons why non-parametric tests are preferred to parametric tests. First, the non-parametric tests are used when data does not have clear arithmetical understanding. Thus, these tests are most suitable when assessing ordinal data. The second reason is that non-parametric tests are...
When we refer to the mechanical properties of materials, whatever crosses the mind is the stress-strain curve. Ideally, both shear stress (σ) and strain (ε) testing are inevitable when it comes to material testing. While shear stress testing correlates the elongation force to the cross-sectional area of a material, tensile...
Impacts of meat production on the environment Different agricultural methods are used for meat production in different regions of the world. However, all the available methods have a number of negative environmental effects. The most common and adverse impacts include air pollution, land degeneration, and water pollution (Adler & Lawler,...
Consider a real scenario where the relationship between a car’s velocity and time is given by ν(t) = t+2, for 0 ≤ t ≤ 5. The following can be defined as follows: Dependent variable: In a function, this is the quantity whose value depends on the value chosen for the...
Research Questions in a Mixed Methods Study The peculiar feature of the study under analysis is that its authors make a decision to employ mixed methods to investigate the ways of how teachers use technologies in the classroom, evaluate internal and external barriers, and achieve a better understanding of the...
Sampling is a significant factor of a scientific approach that determines the validity and reliability of any research. By definition, a sample is a representative group of a population observed to generalize the findings (Ary, Jacobs, Sorencen, & Walker, 2014). The sampling strategy depends on the research design and research...
Introduction Qualitative and quantitative research designs have traditionally dominated public policy research (Morçöl 192). However, they have some specific applications in research because of their differences in style and technique (Islam 23). Based on these differences, researchers have held contradictory opinions regarding their use in public policy studies (Morçöl 192)....
Differences between Quantitative and Qualitative Studies Certain differences exist between quantitative and qualitative research methods. Researchers use qualitative methods to collect, interpret, and analyze data. This method is also subjective. A qualitative approach uses various methods to collect data such as in-depth interviews, observations, and focus groups (Christensen, Johnson &...
Introduction I will be focusing on the article which studies child trend in school environment and adolescence well-being written by Marin and Brown (Marin and Brown, 2008). The study employed quantitative research methodology where the researcher went out to collect data from the field. This research focuses on a broader...
General definition of the types of research methods The Traditional Academic Research method involves elucidating, foretelling and scheming educational experiences (Mills, 2011). There are two methods of data collection that can be used in Action Reaction Research and they are quantitative and qualitative research methods. Quantitative research involves collecting numerical...
