Introduction The crash of the Columbia and Challenger space shuttles is often construed with varied opinions and views among Americans and indeed all people of age and size. The National Aeronautics and Space Administration (NASA), which is the worldwide leader in areas that deal with space science is one of...
Different branches of science have among its purposes one common aim, which is explanation. Different scientific, methods related to different areas of science, tends to describe and frame the unexplained and unknown. In terms of geology and oceanography, one of the subjects attracting the minds of the scientists is concerned...
The impacts of substance abuse on pregnancy have been a subject of many qualitative and quantitative studies. A great number of research works have been dedicated to the description of the complications that can arise due to drug addiction, for instance, outcome of delivery, health of the mother and newborn,...
Building theories allow scientists to study phenomena of the real world by representing them in the form of abstract models. This approach provides researchers with a useful tool that makes it possible to reduce the complexity of the processes in question by focusing on the most relevant aspects of them....
Icebreaker To make sure that the audience is engaged with the subject matter and is ready explore the opportunities that case studies provide, one may consider inviting the participants to take an active part in the deconstruction of the phenomenon of a case study. However, apart from focusing on what...
The choice of the research approach is an important decision because it determines further validity and reliability of the study results. The selected approach, qualitative or quantitative, defines the research design, methods of data analysis, and generalizability of the results. Quantitative research is usually more formal, objective, and applies a...
Introduction Reliability and validity are significant elements of any assessment tool. However thoroughly developed the tools are, if they are not valid or reliable, the research is doomed to fail. Reliability is the rate of consistency which involves the following methods: inter-rater, parallel forms, test-retest, and internal consistency. Validity is...
In order to guarantee that the collected data can be effectively analyzed with the help of quantitative statistical and qualitative tests to provide answers to research questions in nursing, it is necessary to apply appropriate instruments for data collection. The veracity, validity, and reliability of the survey used in the...
Identifying population parameters is essential to the success of a research or the production process (Sharpe, DeVeaux, & Velleman, 2015). Herein the significance of the tools known as confidence intervals lies. Allowing estimating the key parameters of the target population, continence intervals serve as a means of reducing the chances...
The phenomenon of the F statistics is typically referred to as the value retrieved in the course of carrying out an ANOVA test (Hahs-Vaughn & Lomax, 2013). Similarly, the F-statistics-related data can be acquired when running a regression analysis. Seeing that the two tests mentioned above are aimed primarily at...
When conducting research, it is important to reach accurate conclusions and generalizations concerning the participant groups. For this purpose, statistical tests are used, which can be classified into parametric and non-parametric. While for the first type, the researcher is aware of the parameter to be applied to the sample, the...
Testing Hypotheses The process of determining correlations between specific data sets or locating a tendency within one of them is a crucial part of assuring quality in the context of any organization (Groebner, Shannon, & Fry, 2014b). Therefore, it is imperative to make sure that proper statistical tests are applied...
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....
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...
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...
Conversation Analysis (CA) is the technique used to investigate and analyze the structures and processes of social interactions between human beings. CA is primarily focused on casual conversations but it also deals with the non-verbal forms of social interaction. CA’s research methodologies have evolved to include advanced forms of social...
Introduction The contribution made by Muslim mathematicians towards Western civilization cannot be underestimated. Unlike other religions where dogmas are not linked to science, Islam and science are correlated (Ahmed 63). Muslims have contributed greatly to the development of modern science especially in the area of algebra. Muslim mathematicians are the...
Background In this work, it is necessary to test the null hypothesis that urban and rural residents both have the same attitude toward gun control. Accordingly, an alternative hypothesis would be: urban and rural residents do not have the same attitude toward gun control. In this case, there are two...
Introduction It was interesting to determine if the height of girls and boys in adolescence differed. Because growth hormone is produced at high levels during pubertal development, adolescent height changes rapidly (Yau & Rapaport, 2022; Cavarzere et al., 2020). Boys, on average, may be taller than girls physiologically because this...
Introduction The purpose of this work was to study the kinetics of motion of a smart cart, which was propelled by adding the mass of a suspended weight. The cart moved on a horizontal plane without any additional reinforcement; it follows that only the gravity of the weight suspended on...
Testing Hypotheses The process of conducting a hypothesis test is structured into important phases. They are, in order, formulating null (H0) and alternative (Ha) hypotheses, selecting a significance level (α), choosing an appropriate statistical test, collecting data, and computing the test statistic (Anderson et al., 2018). After that, one can...
