unlike quantitative observation. Generally, quantitative observation deals with data that can be counted while qualitative observation deals with data that can be described in terms of the 5 sensory organs. Qualitative research is a descriptive data collection technique used to discover details that help explain behavior. In a health care context, randomised controlled trials are quantitative in nature, as are case-control and cohort studies. Retrospective studies have several chances of bias because first-hand information is not possible in this case. A retrospective case series is the description of a group of cases with a new or unusual disease or treatment. Both methods are primarily defined by specific characteristics in terms of their research design, data sample size and other features already mentioned in this write-up. Surveys (questionnaires) are usually quantitative . There is another class of quantitative research design called non-experimental research. For example, lets say you are researching social interactions among wild cats. Qualitative research gathers data that is free-form and non-numerical, such as diaries, open-ended questionnaires, interviews and observations that are not coded using a numerical system. Longitudinal studies are primarily a qualitative research method because the researcher observes and records changes in variables over an extended period. The difficulty with a randomized controlled trial is that the results may not be generalizable in all circumstances with all patient populations, so as with any research study, you need to consider the application of the findings to your patients in your setting. In a deductive analysis, the researcher develops a research theory, builds hypotheses from this theory and tests the hypotheses by collecting and analyzing data samples using quantitative observation methods. Quantitative observation defines research data based in terms of quantity hence, it utilizes statistical parameters for measurements. Correlational research involves the study of the relationship between two or more variables. Advantages: quick and cheap; only feasible method for very rare disorders or those with long lag between exposure and outcome; fewer subjects needed than cross-sectional studies. When searching for evidence-based information, one should select the highest level of evidence possiblesystematic reviews or meta-analysis.
