Advantages And Limitations Of Qualitative Research

Qualitative research is flexible written form their results are ongoing and their conclusion can be changed while quantitative research is numerical, reliable, specific, data are collected by statistical analysis due to which quantitative are more accurate. Qualitative research uses open questions to find the depth of the information while quantitative research uses closed question, secondary data or experiments due to this it lacks the depth of the information and neglect the effect of the individuals which could be service provider, service users or other staff members.

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

Researchers use a quantitative research approach to test a theory or hypothesis. For example, if a researcher wants to know if students’ grades improve after a certain number of weeks in a math course, the researcher could conduct a statistical analysis using samples of student grades to test the change in students’ grades after a given number of weeks in the math course. Analysis of pre and post-test data on student test scores would yield the information necessary to answer the quantitative research questions. The results of quantitative analyses are then used to make a statistically generalization of the larger population (Yin, 2013; Creswell, 2013). Conversely, if a researcher wants to understand how the study habits of the top performers of a math class differ from the study habits of low performers, he or she could conduct observations and interviews with students to uncover common themes

In research the two main used approaches are qualitative and quantitative. Qualitative research represents the study of perceptions, emotions and experiences in the direction of understanding the human behaviour therefore from a subjective perspective ( R). On the other side the quantitative research is expressed numerical, measurable, appropriate for statistics defined as being objective and can be used for general public (R). Another difference, according to Moule (2015) is that qualitative approach is usually using a smaller sampling size for the study than the quantitative approach. As the qualitative research is inductive, the process is orientated and using a holistic view, allows the researcher

Although qualitative researchers are more likely to come up against the constraints of everyday social life, qualitative research embed their findings within the action of the social world (Lincoln, 2003), in contrast quantitative research seldom studies the world directly.

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.

The researcher must set a clear hypothesis, showing the relationship between independent and dependent variables. In quantitative research tools are used to collect numerical data. The information can be gathered using questionnaires or some type of equipment. Quantitative data is efficient at testing a hypothesis, but can miss contextual detail. In quantitative research, the researcher is often objectively separated from the subject matter. One of the ways quantitative research is different from qualitative research is that quantitative research requires extraction of large amounts of statistical data. Qualitative research is focused in on personal viewpoints and opinions of a smaller number of subjects (typically). Qualitative research can take more time than quantitative research (McCusker & Gunaydin,

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.

There are many benefits of utilizing quantitative methods in research. The benefits are precise numerical data, previously constructed theories can be tested and validated, results can be generated from sufficient random samples sizes, and less time is needed for data analysis. The weaknesses of quantitative methods are that due to the focus of the theory used the researcher may miss phenomena occurring, or the information gained may be too general to be applied to the individuals. The other weaknesses are colleagues may not understand the categories used, and colleagues may not understand the theories used by the researchers. (Zikmund et al, 2010) Qualitative Methods

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.

There are different ways in which researcher defines quantitative and qualitative research. Quantitative research is a social research that uses experimental methods, questionnaires, numerical data and explains observations usually in tables or charts from. Quantitative research can define the relationship between two or more studies.

Moreover, the quantitative method is used by researches who want to discover statistics and facts by analyzing data in a numerical way. Unlike this article, the qualitative method is used by researches who want to gather data through observations and interviews based on what the participants say or do. The qualitative method seeks to explore and collect opinions and motivations on the research topic instead of collecting numerical data.

Quantitative research is gathered using a traditional tactic, that is a calculated way of obtaining data (Polit & Beck, 2017). Data

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.

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
