Examine the Fields of Qualitative and Quantitative Research and the Advantages and Limitation of Each Paradigm.

The theoretical foundations of qualitative and quantitative methods are very different, but many researchers believe both methods should be used in the research study to increase validity and reliability.

Quantitative and qualitative research generates from two different perspectives, and it provide different types of crucial information from the research subject. Qualitative research corresponds more with comprehensive and thorough descriptions of events, whereas quantitative research creates statistical models to explain events. Several advantages and disadvantages in qualitative and quantitative research, depends upon the researcher's purpose and area of focus and information that will answer those research questions (Creswell, (2013).

The key distinctions between qualitative and quantitative data are qualitative data is subjective, ask What?, Why?, literature review may be done after study is complete, develops theory, focus is complex, facts are biased and values are involved, qualitative data is about discovery, describing, understanding, sharing results to who are concerned about the study. Basic with analysis is part of, the researcher conducting the study is part of the process, and participants are involved, reasoning is dialectic and inductive, describes the meaning of what was discovered in the study conducted, uses communication and observation, and strives for trends and theories easy to understand. Study conducted has a flexible approach in a natural setting, provides information worth counting (Anderson, 2006). Quantitative data provides objectives, ask questions how many?, literature review must be done early in the study, tests theory, focus is

A qualitative study addresses the complexity of human experience, focusing on the big picture (Rebar & Gersch, 2015); while a quantitative study breaks a problem down into small pieces and focuses on specific parts to see how they all relate (Rebar & Gersch, 2015). Qualitative methods focus on subjective information, and never try to predict or control the phenomenon of interest (Rebar & Gersch, 2015); on the other hand, quantitative methods focus on statistics and objective information, and can yield predictions and control (Rebar & Gersch, 2015).

According to Kothari (2008) qualitative research is concerned with qualitative phenomena which are related to or involve quality or kind. Qualitative research engages the collection and analysis of non-numerical data obtained from experiments, interviews, observations, and other resources involving statements and arguments. Research is conducted into particular context and non-numerical interpretive approach is used to produce narrative description of research data. Unlike quantitative research, this type of research considers the underlying facts behind the establishment of particular behaviors and assumptions. It is commonly used in behavioural sciences where the aim of research is to discover underlying motives of human behaviour.

Research methodology generally involves qualitative research or quantitative research, or a mixture of both. A quantitative research methodology involves the analysis of data collected from a large number of surveys or interviews. On the other hand, methodologies for qualitative research often involve using surveys or interviews to collect information about people — their attitudes, experiences and behaviors.

This paper primarily concerns qualitative research, but we were asked to compare both qualitative and quantitative methods. During comparison, there are many noted differences in both study designs, but not many similarities. Qualitative research uses a subjective approach with a large sample population. It collects non-statistical data, using an unstructured or semi-structured technique (Nieswiadomy & Bailey, 2018). Quantitative research uses an objective approach and large, random, sampling to ask opinions in a structured way. The findings of quantitative studies are conclusive and used to recommend a final course of action (Nieswiadomy & Bailey, 2018). While it is hard to see similarities between the two, both methods aim to find a solution to a problem or question, the researcher doing the study may affect the outcome and an analysis of the collected data must be done (Souza, 2017). What many don’t realize is the connection amongst the two. You can say, both types of research build upon one another, meaning quantitative studies can quantify results found in qualitative research (Souza, 2017).

Researchers are sometimes using Quantitative and Qualitative research methodologies interchangeably, or all three of the methodologies including the mixed approach, Creswell (2009). However, the most distinctive differences between the two is the application used, or the design, using words for qualitative analysis, and

Qualitative and quantitative methods each bring a unique perspective to research and both methods satisfy the major goals of research in different ways.

General speaking, quantitative research is thought to be objective, however qualitative research often involves a subjective element. There are differences designs in qualitative research in comparison to quantitative research. Qualitative research involves words, pictures, or objects; Quantitative involves data in the form of numbers and statistics.

Quantitative and qualitative methods differ from one another as to their research design elements as listed below:

“Researchers who use quantitative research method seek objectivity through testable hypotheses and carefully designed studies, and gather date that can be reported in numbers and statistics” (Crawford, 2016, p. 66). According to Crawford (2016, p. 66) “conclusions from this study are drawn from statistics and generalized to populations of interest”. Unlike qualitative that helps to eliminate opinions and thoughts, quantitative quantify opinions and thoughts and they obtain results from a larger sampling population. As I had previously stated on my discussion board “Quantitative researcher’s collection methods include many different kinds of surveys for example; online surveys, paper surveys, online polls, face-to-face interviews, telephone interviews, and etc”(myself). “They use the surveys to measure attitudes, behaviors, and opinions” (myself).

Due to my biases as a social worker, I favored qualitative research methods more compared to quantitative research methods. However, after taking this course I have grown to like and appreciate quantitative research methods. As mentioned each have there are strengths and limitation.

There are also some differences between these study designs, which may cause some problems for the inexperienced researcher. “Quantitative research is objective; qualitative research is subjective. Quantitative research seeks explanatory laws; qualitative research aims at

(i) Quantitative vs Qualitative Research: Qualitative research methods is based on values and not numbers while quantitative is based on numeric and Quantifiable data to generalize in its conclusion.
