Quantitative and Qualitative Research Methods Research work in social work is either qualitative or quantitative in nature. Qualitative research, according to Neill (2007, p. 1) is used when the data that is gathered, or the research that has been performed, can not be quantified or assigned numerical weight. For example,...
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,...

Introduction Albert Einstein was born on March 14,1879 at Ulm, in Wurtemberg, Germany. He was the most recognized scientist in history. As a child, Einstein had speech difficulties, but he was also the top student in his elementary school (Rosenkranz, Ze’ev, 2005). Initially, Einstein started taking interest in deductive reasoning...
Sample and Setting The researcher will sample nurses and congestive heart failure patients at Jackson Memorial Hospital in Miami, Florida. Nurses will be sampled from the hospital’s department of cardiology. They have to have worked in this department for at least five years. They will provide their expert opinion on...
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...
How does a research problem/question guide the determination to conduct a quantitative versus a qualitative research study? The research question directly correlates with the type of relationship under investigation. Quantitative and qualitative studies differ in their approach to examining relationships (Polt & Beck, 2017). Therefore, selecting a quantitative study for...
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...
A research question that can be addressed by a two-way factorial ANOVA is as follows: Is there an interaction between a person’s gender and their level of education that results in differences in the levels of depression between different groups? A factorial ANOVA would be an appropriate analytical method for...
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...
