Experimental methods limit the possible ways in which a research participant can react to and express appropriate social behavior. Findings are therefore likely to be context-bound and simply a reflection of the assumptions which the researcher brings to the investigation. Statistics help us turn quantitative data into useful information to help with decision making. We can use statistics to summarise our data, describing patterns, relationships, and connections.
Statistics can be descriptive or inferential. Descriptive statistics help us to summarise our data whereas inferential statistics are used to identify statistically significant differences between groups of data such as intervention and control groups in a randomised control study. Quantitative experiments do not take place in natural settings.
In addition, they do not allow participants to explain their choices or the meaning of the questions may have for those participants Carr, Poor knowledge of the application of statistical analysis may negatively affect analysis and subsequent interpretation Black, Variability of data quantity: Large sample sizes are needed for more accurate analysis.
Small scale quantitative studies may be less reliable because of the low quantity of data Denscombe, This also affects the ability to generalize study findings to wider populations.
The researcher might miss observing phenomena because of focus on theory or hypothesis testing rather than on the theory of hypothesis generation. Sophisticated software removes much of the need for prolonged data analysis, especially with large volumes of data involved Antonius, Quantitative data is based on measured values and can be checked by others because numerical data is less open to ambiguities of interpretation.
Hypotheses can also be tested because of the used of statistical analysis Antonius, Doing quantitative research in the social sciences: An integrated approach to research design, measurement and statistics. Using thematic analysis in psychology.
Qualitative Research in Psychology , 3, 77— The strengths and weaknesses of quantitative and qualitative research: Journal of advanced nursing, 20 4 , The Good Research Guide: Handbook of Qualitative Research. The discovery of grounded theory; strategies for qualitative research.
Nursing research, 17 4 , It provides insights into the problem or helps to develop ideas or hypotheses for potential quantitative research. Qualitative Research is also used to uncover trends in thought and opinions, and dive deeper into the problem. Qualitative data collection methods vary using unstructured or semi-structured techniques. The sample size is typically small, and respondents are selected to fulfil a given quota.
Quantitative Research is used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics. It is used to quantify attitudes, opinions, behaviors, and other defined variables — and generalize results from a larger sample population. Quantitative Research uses measurable data to formulate facts and uncover patterns in research.
Quantitative data collection methods are much more structured than Qualitative data collection methods. Quantitative data collection methods include various forms of surveys — online surveys, paper surveys , mobile surveys and kiosk surveys, face-to-face interviews, telephone interviews, longitudinal studies, website interceptors, online polls, and systematic observations. Snap has many robust features that will help your organization effectively gather and analyze quantitative data.
While defining quantitative and qualitative research based on their uses and purposes may be considered a practical approach for researcher, the difference actually lies on their roots: Procedures, designs, concepts, purposes and uses emanate from there. Example on qualitative research referring to quality where problems are answered without generally focusing on quantity, are descriptions in words coming form interviews, discussions or observations.
However when words are translated to quantity in order to describe or to generalize, then the research is now called quantitatitive research. The bottom lines are the questions: Many thanks for giving me clear understanding around the differences between the qualitative and quantative research.

When to Use Quantitative Methods This module describes when to choose quantitative methodology in research and explores the difference between qualitative and quantitative research. Compare and contrast quantitative and qualitative research methods.
Describe when quantitative research methods should be used to examine a research problem. Provide examples of the appropriate use of quantitative research methodology. Researchers should begin by asking themselves the following questions: What type of question am I asking? What type of data will I need to collect to answer the question? What type of results will I report? Planning, conducting, and evaluating quantitative. Qualitative, quantitative, and mixed methods approaches.
A model comparison approach.
What’s the difference between qualitative and quantitative research? Susan E. DeFranzo September 16, Many times those that undertake a research project often find they are not aware of the differences between Qualitative Research and Quantitative Research methods.
Quantitative Methods Methods include focus groups, in-depth interviews, and reviews of documents for types of themes Surveys, structured interviews & observations, and reviews of records or documents for numeric information.
Qualitative research is inductive and does not require a hypothesis in order to start the research process. Let's take a closer look at this important difference, and dig a bit deeper into three key terms that help define quantitative and qualitative research. Quantitative research is “explaining phenomena by collecting numerical data that are analysed using mathematically based methods (in particular statistics). Qualitative research seeks to answer questions about why and how people behave in the way that they do.
Qualitative Research is ideal for earlier phases of research projects while for the latter part of the research project, Quantitative Research is highly recommended. Quantitative Research provides the researcher a clearer picture of what to expect in his research compared to Qualitative Research. A good example of a qualitative research method would be unstructured interviews which generate qualitative data through the use of open questions. This allows the respondent to talk in some depth, choosing their own words.
