is retrospective study qualitative or quantitative

However, when a researcher measures the number of variables using fixed numerical or statistical parameters, then this is quantitative observation. Epub 2020 Dec 29. A cross-sectional study is a type of observational study in which the researcher collects data from variables at a specific moment to establish a relationship among them. In some cases, the researchers can spend years documenting the changes among the variables plus their relationships. He records information like how much they weigh, the number of carbs in their diet, and the like at different points. Qualitative observation methods are fluid and do not have any definite parameters for data description hence, the data gathering process is largely subject to the discretion of the researcher. Follow up; measure the outcomes using records, interviews or examinations. A retrospective study is an analysis that compares two groups of individuals. In prospective studies, individuals are followed over time and data about them is collected as their characteristics or circumstances change. If a researcher needs to categorize his or her data sample based on statistical parameters, then quantitative observation would be utilized. The study used a mixed methods approach where qualitative data to helped explain, or elaborate on, the quantitative findings. On the other hand, quantitative research requires a shorter time frame and results in more definite research outcomes. This provides researchers with enough information for arriving at objective findings. Quantitative research is the process of collecting and analyzing numerical data. Periodically, you collect the same types of data from the group to track their development. If you want to have first-hand, factual information about the changes in a sample population, then you should opt for a panel study.

Qualitative observation methods typically entail the researcher recording the research variables in their natural environment. In this approach, we want to understand and describe the lived experience or meaning of persons with a particular condition or situation. A retrospective study uses existing data that have been recorded for reasons other than research. We could use a research tool, such as a Likert scale (5 = very satisfied and 1 = very dissatisfied), to help us gain an understanding of how satisfied nurses are as a group with this policy. 2022 May;161:265-274. doi: 10.1016/j.wneu.2021.12.014.

The expertise and perspective of the researcher may strongly influence the interpretation of results and the conclusions reached, as personal bias can be hard to manage. Finally, the researcher measures the variables again to ascertain how the intervention affected the variables.
