Critiquing qualitative research is far harder than quantitative research as there are just so many different ways that qualitative research can be done. So if you are unfamiliar with the methods that have been used then it may make it very difficult indeed to undertake your qualitative research critique.
Quantitative research is generally closely affiliated with ideas from 'the scientific method'which can include: The generation of models, theories and hypotheses The development of instruments and methods for measurement Experimental control and manipulation of variables Collection of empirical data Modeling and analysis of data Quantitative research is often contrasted with qualitative researchwhich purports to be focused more on discovering underlying meanings and patterns of relationships, including classifications of types of phenomena and entities, in a manner that does not involve mathematical models.
Although a distinction is commonly drawn between qualitative and quantitative aspects of scientific investigation, it has been argued that the two go hand in hand. Although quantitative investigation of the world has existed since people first began to record events or objects that had been counted, the modern idea of quantitative processes have their roots in Auguste Comte 's positivist framework.
Positivist scholars like Comte believed only scientific methods rather than previous spiritual explanations for human behavior could advance. Quantitative methods are an integral component of the five angles of analysis fostered by the data percolation methodology,  which also includes qualitative methods, reviews of the literature including scholarlyinterviews with experts and computer simulation, and which forms an extension of data triangulation.
Quantitative methods have limitations. These studies do not provide reasoning behind participants' responses, they often do not reach underrepresented populations, and they may span long periods in order to collect the data.
Statistical methods are used extensively within fields such as economics, social sciences and biology. Quantitative research using statistical methods starts with the collection of data, based on the hypothesis or theory.
Usually a big sample of data is collected — this would require verification, validation and recording before the analysis can take place. Causal relationships are studied by manipulating factors thought to influence the phenomena of interest while controlling other variables relevant to the experimental outcomes.
In the field of health, for example, researchers might measure and study the relationship between dietary intake and measurable physiological effects such as weight loss, controlling for other key variables such as exercise.
Quantitatively based opinion surveys are widely used in the media, with statistics such as the proportion of respondents in favor of a position commonly reported.
In opinion surveys, respondents are asked a set of structured questions and their responses are tabulated. In the field of climate science, researchers compile and compare statistics such as temperature or atmospheric concentrations of carbon dioxide.
Empirical relationships and associations are also frequently studied by using some form of general linear modelnon-linear model, or by using factor analysis. A fundamental principle in quantitative research is that correlation does not imply causationalthough some such as Clive Granger suggest that a series of correlations can imply a degree of causality.
This principle follows from the fact that it is always possible a spurious relationship exists for variables between which covariance is found in some degree. Associations may be examined between any combination of continuous and categorical variables using methods of statistics.
Measurement[ edit ] Views regarding the role of measurement in quantitative research are somewhat divergent. Measurement is often regarded as being only a means by which observations are expressed numerically in order to investigate causal relations or associations.
However, it has been argued that measurement often plays a more important role in quantitative research. This is because accepting a theory based on results of quantitative data could prove to be a natural phenomenon.
He argued that such abnormalities are interesting when done during the process of obtaining data, as seen below:Description: Historical Social Research – Historische Sozialforschung (HSR) is a peer-reviewed international journal for the application of formal methods to torosgazete.com methods can be defined as all methods which are sufficiently intersubjective to be realized as an information science algorithm.

These two questions appear to be consistent with the study's subject. Characteristics of focus groups. The design of focus group research will vary based on the research question being studied. Below, we highlight some general principles to consider.
