Concepts And Assumptions While Conducting Research

Quantitative research is done to find the accurate facts by evaluating the problems like opinion, behaviour by using numerical data. This research is based on theories, hypothesis, collecting, analysing the data to make the research accurate.

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).

Methods used in psychological research are used to obtain quantitative or qualitative data. Quantitative data is more often than not derived from methods such as experiments and statistics analysing data using surveys, questionnaires and interviews. Qualitative data tends not to be aimed at finding exact measurements in its findings, but is more concerned with evidence collection and analysis through practices such as observation and ethnography (using observations through involvement in activities over a period of time) (Brownlow 2011).

Quantitative research methods are objective as it uses measurements and analysis of statistical data to answer the study question. The researchers’ opinions do not affect the outcome of the study, ensuring that the study is unbiased. Another advantage is quantitative research uses numbers and statistics which is understood universally (Houser,2008).

A quantitative study has objective stances, logic, and numbers focusing on unchanging data and details (Babbie, E.R., 2010). The aim of quantitative research is to classify features, count the features, and construct statistical models to explain what was observed (McNabb, D.E., 2008). It has eight characteristics:

Quantitative and qualitative methods are the forms of collecting evidence and information. In quantitative research, concepts are assigned numerical value, and concerned with measuring social, or criminal justice reality (Hagan, 2010, p. 14).  In qualitative research, concepts are viewed as sensitizing ideas or terms to enhance understanding of reality under investigation (Hagan, 2010, p. 14).  Qualitative research explains an idea, which attempts to show understanding or empathy. This is where the researchers surround themselves within the subject matter and begin to develop an empathetic understanding. The quantitative approach favors studying “phenomena that can be measured, observed, and examined empirically” (Hagan, 2010, p. 14).

“Quantitative research involves numbers and measuring quantitative or amounts”. (Whitehouse, M, 2010:425). Methods that involve quantitative data may

Quantitative research deals with numbers and is measurable. Some examples of quantitative data are cost, number of participants and time. This type of research is systematic and uses the more traditional scientific method of data collection and presentation. Qualitative research has data that is nonnumeric in nature and it is difficult to measure. As the root of the same suggests, it gives a quality description of the data being viewed. It can include descriptions or verbal responses. Qualitative data is subjective in the sense that the answer can be different amongst various people.

In defining quantitative research the term can be dichotomized. Firstly, research refers to creative, systematic work with the intention to increase the knowledge of man and thereby devise new applications (OECD, 2002). In addition Gray (1997) stated that research should improve performance and that the results should be

Quantitative research involves collection of data using a survey technique from human participants. Major benefit of human participants is that a researcher will be able to collect valid and reliable

“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).

Quantitative research: In quantitative researches, surveys are conducted to collect numerical data. Most of the surveys include close-ended questions which are less time consuming. It is quite easy to collect such data as consumers tend to be more co-operative. The collected data is further analyzed for a proper conclusion.

Quantitative research involves collecting data, which can be expressed numerically. The design is well structured with pre-determined outcomes. It frequently involves testing a hypothesis, which then can be analysed from the data deductively using statistical methods. Using numerical data is easier to analysis mathematical, so larger sample sizes can be utilised compared to qualitative research, therefore giving a better representative of the population; along with simplifying the process of making a generalisation. Another advantage is that studies can easily compare to similar findings (Kruger, 2003). The disadvantages are the results are limited and might not provide a proper understanding of the topic. Also, statistics and leading questions can be used to give a false representation of the data when summarising.

One of the trends over the past decade has been the growing use of and interest in qualitative research for educational research. Qualitative research, broadly defined, means "any kind of research that produces findings not arrived at by means of statistical procedures or other means of quantification. Where quantitative researchers seek causal determination, prediction, and generalization of findings, qualitative researchers seek instead illumination, understanding, and extrapolation to similar situations. Qualitative analysis results in a different type of knowledge than does quantitative inquiry. " (Hoepfl, 1997) "During the past several decades, particularly during the 1970s and 1980s, naturalistic

A paradigm is essentially what guides the research conducted by a researcher. Qualitative and quantitative are the main two research paradigms that guide a researcher. These are basically beliefs about reality or ontology. This is called relativism and in this paradigm, the researcher believes that there are many qualitative perspectives of reality. Generally this type of research is subjective. Qualitative research analysis is generally inductive and focuses on experiences and perceptions of research participants. Research design methods for this paradigm include phenomenology (lived experience), ethnography (influence of culture) and grounded theory (social process) (NurseKillam, 2017).
