A cohort study entails collecting information from a group of people who share specific traits or have experienced a particular occurrence simultaneously. The three main types of longitudinal studies are: These methods help researchers to study variables and account for qualitative and quantitative data from the research sample. Quantitative observation defines research data based in terms of quantity hence, it utilizes statistical parameters for measurements. There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research. Results can be clearly communicated through statistics and numbers. FOIA A cohort is a defined group, like "nurses," "10-19 year-olds," or "college students.". Qualitative study generally falls under three types of designs: phenomenology, ethnography and grounded theory. In other words, quantitative and qualitative observation helps the researcher to gather the information that would later be analyzed in order to come up with research findings. Disadvantages of Retrospective Study It is easily affected by recall bias or misclassification bias.
