There are quantitative and qualitative methods in the realm of academic research seem to be the most relevant to the domains of professional study at Henley-Putnam University. These methods involve the collection of different types of data to help better understand the world around us. Quantitative research is associated with the hard sciences such as chemistry, engineering, and mathematics such as measuring items quantitatively can consist of observing the distance between planets as they revolve around the sun or recording the pressure within a closed container as heat is introduced to a particular liquid. In other words, quantitative methods allow for measuring one thing to compare against another known or unknown quantity to generate conclusions, sometime confirming hypotheses or creating new ones based on research outcomes. However, qualitative research is applied in the soft or social sciences, such as history, sociology and anthropology. According to Qualitative Research Consultants Association (QRCA), qualitative research seeks out the “why”, not the “how”, of its topic through the analysis of unstructured information. For instance, methodological discussions like how data is collected and analyzed. Qualitative research does not rely on statistics or numbers, which are the domain of quantitative researchers.
There is a debate between Quantitative and Qualitative methodologies to compare which is more appropriate or which produces better insight or which is best
According to Yin (2003), there are two types of research approach. This includes quantitative research approach and qualitative research approach. A quantitative research emphasizes on transforming the data to numbers, quantities and statistics to formulate facts and to uncover patterns in a research. It addresses research purposes through empirical analysis that involve numerical measurement, the relationship between variables and analysis approaches (Zikmund et al., 2010). The sample size being investigated is typically large (Anderson, 2006). Quantitative research mainly uses questionnaires, surveys and other equipment to collect numerical or measurable data (Anderson, 2006). On the other hand, a qualitative research typically emphasizes words more than numbers
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).
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.
For quite a while there has been some discussion around which method of distinctions between Qualitative research and quantitative research. This has been fired in later years with some thinking that a combination of the two is best practice especially in social
Researchers often times are faced with the decision of choosing a methodology of research; either Quantitative or Qualitative that they think best fits their study and objectives. This choice is guarded by the topic of study, the advantages and disadvantages, and the strengths and weaknesses of using either one or the other type of the methodologies.
Quantitative and qualitative methods differ from one another as to their research design elements as listed below:
It is common for researchers to compare qualitative and quantitative research methods. Quantitative methods originate from positivist and post- positivist research paradigms. Also, the methods objectively examine statistical data to determine cause and affect and often use generalizable data. There are various methods used in quantitative research such as surveys,
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).
Qualitative and quantitative research are methods used in Sociology to explain and describe data. However, these methods contrast in different important aspects.
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.
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.
Quantitative research is considered to be the use of numbers. In the use of a quantitative study, the researcher test objective theories by examining the conjunction among variables. The variables used can be measured on instruments, so that numbered data can be used and analyzed (Creswell, 2008). Qualitative research is mainly used to explore and understand human or social problems. The process of qualitative studies includes questions and procedures; and the data is collected byway of participant’s settings. It allows the researcher to study an issue in great detail and depth, as well as not allowing data collection to be constrained by predetermined data. Mixed methods research combines quantitative and qualitative methods and it involves philosophical assumptions. This form of study includes collecting and analyzing data from a quantitative and qualitative perspective. It is believed that mixed methods research is a great method for practicing researchers who would like to bridge the schism between quantitative and qualitative research (Onwuegbuzie & Leech, 2004a). Even though these methods are different, they all involve philosophical assumptions and distinct methods or procedures (Cresswell, 2009).
Defining Qualitative are dynamic they change because situations are not static and they having multiple realities, none of which is more valid or true than another. The purpose of qualitative methodology is to explain and get insight and understanding or description. By cautious and extreme literature review and data collection, which create hypotheses assumptions and the hypotheses are tested such inductive inferences develop while in contrast quantitative research methodology prevent relatively change in situation and events and it is depend on single reality which researcher ensure generalization and understanding. The aim of quantitative methodology in research is to predict the situation or event by the statistical testing of variables, whether they have correlation or not this is focused on numerical data such hypotheses are tested and develop deductive conclusion of the situation and event.
(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.
