Research design is very critical in determining the validity, reliability, and generalizability of the findings. For the research findings to be credible, they must pass statistical tests of validity, reliability, and generalizability. Since positivists support the use of empirical evidences in the criminal justice system, they apply statistical tests quantitatively...
Such issues as the credibility and validity of qualitative research have been discussed for decades (Creswell, 2007; Patton, 2002). Many researchers argue that qualitative research is often associated with misinterpretation. Admittedly, it is rather difficult to remain unbiased as even researchers are subjected to the influence of various factors. Nonetheless,...

The author starts the article by highlighting the importance of voice in everyday communication, particularly the fact that it can be used to define the communicative distance between the listener and the talker. He states the aim of the article as being an attempt to address the difficulties arising out...
A researcher carrying out qualitative research has to pay specific attention to credibility and dependability. These two aspects form the validity of the research. It is necessary to note that different scholars have come up with various definitions (Winter, 2000). In simple terms, credibility refers to the accuracy of 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,...
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...
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...
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...
The issue of travelling in time is not new because it has interested people for centuries and continues interesting us today. However, in spite of people’s high concern and eagerness to uncover time’s mysteries, it still keeps its secrets as it did centuries ago. Even in our time, when a...
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 This paper provides an in-depth overview of the Upper 11-Abercrombie site in New South Wales, Australia. Its primary goal is to provide colleagues with essential knowledge before conducting field surveys to determine instream and riparian health. This introduction provides an overview of the site’s geographic coordinates, with a focus...
Introduction A population refers to the entire group about which a researcher wants to draw generalizations, while a sample entails a particular group from which a researcher will collect data. It is always the case that the sample size is less than the total size of a population in a...
Introduction As humanity’s intrinsic curiosity drives a desire to learn more about the universe beyond what is currently understood, the idea of extraterrestrial beings has perplexed cultures for decades. Scientists worldwide have repeatedly studied the mystery of extraterrestrial existence through numerous initiatives, all aimed at finding a definitive solution to...
Experiment Components An experiment is a systematic technique used to confirm, deny, or prove the truth of a hypothesis. Experiments demonstrate what happens when a specific factor is modified, shedding light on cause-and-effect relationships. The Independent Variable is an experiment’s first essential component (IV). The experimenter manipulates or modifies the...
Introduction The purpose of this proposal is to examine the characteristics of four lenses: social science, natural science, history, and the humanities. In addition to general knowledge, the similarities and differences between these aspects will be investigated after understanding the lenses and their types of evidence. At the end of...
The Importance of Mathematics in Classical Education One of the fundamental components of classical education is consistently emphasized, which is mathematics. Experts think it fosters a feeling of wonder in kids that grows with time, enabling them to expand their knowledge in other fields and discover more important information. It...
Research Question The research question for this study is: “Does the amount of time spent on physical exercise influence the level of stress in working adults?” In the context of working adults, this question examines whether physical activity is associated with stress levels. Type of Research This study exemplifies applied...
Introduction Volcanoes in Hawaii represent a special type of geological activity. They were well-known to every islander and of particular scientific interest. They are the result of geological changes that take place beneath the Hawaiian Islands and at the bottom of the Pacific Ocean. Hawaiian volcanoes also have a significant...
Research Question and Hypotheses Research question: Is the mean monthly salary of male CEOs in the United States higher than that of females? Ho (null hypothesis): The average monthly salary earned by male CEOs in the U.S. is statistically no more than the average monthly salary earned by their female...
Introduction The field of mathematics has grown tremendously over the centuries. Incorporating the theoretical and practical concepts introduced by numerous civilizations, this area of study became capable of addressing humanity’s modern needs. Both Greece and Egypt are well remembered for their significant contributions to mathematics and their extensive use of...
Introduction Every credible study requires a thorough research methodology, as it is from this process that scholars can identify, select, process, and assess the information. In research articles, the methodology section allows the reader to critically examine the report’s validity and reliability. A recent study that aims to improve firms’...
Introduction Data is a critical component of solving any problem a person may encounter. It is precious and helps make decisions on any topic, but without statistics, it will not make sense (Crash Course, 2018). Such a discipline is essential in almost every science due to the opportunities it gives....
