The Importance of Quantitative Methods in Environmental Science and Sustainability Measurement. Qualitative measures are often contrasted with quantitative measures. Experiments and surveys – the principal research designs in quantitative research – are described and key features explained. Quantitative research is an inquiry into an identified problem, based on testing a theory, measured with numbers, and analyzed using statistical techniques. Interval data are quantitative data that have the same and fixed distance between one point and another on the measurement scale. A questionnaire is a collection of a set of questions.

Why? ... Take Quantitative Research as a standalone course or as part of the Market Research Specialization. In applied social research most “count” variables are ratio, for example, the number of clients in past six months. The concepts of dependent and independent variables are addressed and the concept of measurement and its associated issues, such as error, reliability and validity, are explored. Quantitative research is used by social scientists, including communication researchers, to observe phenomena or occurrences affecting individuals. Weight is a ratio variable. So I thought it would be helpful to dive a little deeper into the two types of research scales I touched on in my last post. In a future column, we will explore the types of answers possible for qualitative research. A ll researchers must deal with questions related to their unit of analysis and the related idea of unit of observation. It can be qualitative or quantitative. However, qualitative research is used when the researcher has no idea what to expect. The purpose of research is to answer questions. A survey, on the other hand, includes the process of making the questionnaire, collecting the responses, aggregating the data and analysing it (SurveyMonkey, 2019). Quantitative data is defined as the value of data in the form of counts or numbers where each data-set has an unique numerical value associated with it. • The overarching aim of a quantitative research study is to classify features, count them, and construct statistical models in an attempt to explain what is observed.
