Qualitative research explores the complexity, depth, and richness of a particular situation from the perspective of the informantsreferring to the person or persons providing the information. A retrospective study uses existing data that have been recorded for reasons other than research. Usually, qualitative observation is more time-consuming, extensive and personal, and it uses the 5 sensory organs while examining research variables.

In the course of a qualitative study, the researcher may conduct interviews or focus groups to collect data that is not available in existing documents or records. The data gathered using quantitative observation is usually accurate since it is subject to a few research biases. For example, when a researcher pays equates research variables in terms of their quality, then this is qualitative observation. What makes it "retrospective" is that you are working from effect to cause, not vice-versa. Disadvantages of Retrospective Study It is easily affected by recall bias or misclassification bias.
