The Difference Between Qualitative & Quantitative Measurement Quantitative research is a research strategy that focuses on quantifying the collection and analysis of data. Measurement instrument refers to various methods through which a researcher obtains data from respondents for his research work. Qualitative research seeks answers to question in a systematic manner to generates findings that are applicable beyond the immediate boundaries of this research and that the researcher cannot determine in advance. Data Gathering Instrument – Quantitative Research makes use of tools such as questionnaires, surveys, measurements and other equipment to collect numerical or measurable data. Realism, subjectivism and the ‘paradigm wars’ Now we have defined quantitative research, it is a good idea to compare it with qualitative research, to which it is usually put in opposition. In a future column, we will explore the types of answers possible for qualitative research. Unit of analysis helps the researcher define what is being studied as well as what aspects are being studied. 311. Quantitative research is more preferred over qualitative research because it is more scientific, objective, fast, focused and acceptable. Scales of measurement in research and statistics are the different ways in which variables are defined and grouped into different categories. Quantitative outcome research is mostly conducted in the social sciences using the statistical methods used above to collect quantitative data from the research study. Learn vocabulary, terms, and more with flashcards, games, and other study tools. This article describes the basic tenets of quantitative research. Interval data are quantitative data that have the same and fixed distance between one point and another on the measurement scale. For example the size of the air temperature expressed in units of centigrade. 1 comment. 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. Ratio data is quantitative data that has a zero point and a ratio between two significant data values. However, qualitative research is used when the researcher has no idea what to expect. Importance of Quantitative Research. Finally, in ratio measurement there is always an absolute zero that is meaningful. ... quantitative methods based on rigorous scientific research are crucial for establishing an evidence-based consensus on pertinent issues that provide a foundation for meaningful policy implementation.
