Some limitations are that quantitative research methods take snapshots of a phenomenon: not in-depth, and overlook test-takers’ and testers’ experiences as well as what they mean by something. The following are some of the important limitations of quantitative methods: Quantitative methods involve the use of mathematical models, equations and other mathematical expressions, which are derived on the basis of several assumptions. For all of these variables the response is going to be a number or value. analysis are very useful Quantitative techniques. Quantitative methods are essentially a variety of research techniques that are used to gather quantitative data. can be studied. Some specific limitations associated with using quantitative methods to study research problems in the social sciences include: Quantitative data is more efficient and able to test hypotheses, but may miss contextual detail; Uses a static and rigid approach and so employs an inflexible process of discovery; Definite economic problems can very rarely be dealt with by merely quantitative methods. Methods such as questionnaires in quantitative research are quite inflexible and often require large samples. Applications of Quantitative Techniques. Quantitative research method involves structured questionnaire with close ended questions. Quantitative Data can be divided into two types, namely; Discrete & Continuous Data. False focus on numbers. Also, the respondents have limited options of responses, based on the selection made by the researcher. 5. Methods Assessment methods (also called techniques or instruments) include both direct and indirect approaches. Quantitative Techniques. For example, research studying the morphology and mechanism of action of SARS-CoV-2 is descriptive. Qualitative research can be used to understand how an individual subjectively perceives and gives meaning to their social reality. Its application is restricted in areas that deal with human behaviour. Classification of data, types of data/series etc. The general purpose of quantitative research is to investigate a particular topic or activity through the measurement of variables in quantifiable terms.

Primary vs Secondary Data and their collection methods, Different graphs and their examples. While the census aims to gain universal response it is still a sample size unless the entire population is polled. Qualitative and quantitative data research are the two main types of research design. This double edged sword leaves the quantitative method unable to deal with questions that require specific feedback, and often lacks a human element. A quantitative research method is used to collect and analyze numerical data. Quantitative Disadvantages Survey instruments are vulnerable to errors such as mistakes in measurement and flawed sampling techniques. The mixed methods approach includes a multiple level strategy incorporating a two phase approach where (for example) quantitative research is undertaken first, followed by qualitative research; a systematic and planned approach to … Possible Limitations of the Researcher. Answers to questions like ‘How much’, ‘How many’, ‘What percentage’, and ‘How often’ are what constitutes quantitative data. These statistics are often then used for research and analysis leading to business decisions. Quantitative research methods, on the other hand, involve a larger sample, and do not require relatively a longer time for data collection. You cannot follow-up on any answers in quantitative research. By using the methods of statistics, the problems regarding production, income, price, wage, height, weight etc. "Quantitative research," also called "empirical research," refers to any research based on something that can be accurately and precisely measured. Quantitative Research is a systematic investigation of phenomena by gathering quantifiable data and performing statistical, mathematical, or computational techniques. The quantitative research is anonymous in nature. Data from quantitative research—such as market size, demographics, and user preferences—provides important information for business decisions. Qualitative research interviews, for example, are less structured than their quantitative equivalent, and consist ideally of an exchange of ideas between the researcher and the interviewee on a particular theme. Quantitative data lends itself to statistical analysis, while qualitative data is grouped according to themes. Regardless of the methodology being used, all of the samples have to be representative.
