Quantitative designs can be experimental, quasi-experimental, descriptive, or correlational. In terms of similarities, both qualitative and quantitative observation methods depend on participants and groups in order to gather research variables. These methods help researchers to study variables and account for, to gather information from a fixed number of variables at regular but distant intervals, often spinning into a few years. In fact, most researchers believe that a randomized controlled trail is the only kind of research study where we can infer cause (if A, then B). a observational study is where nothing changes and just record what you see, but an experimental study is where you have a control group and a testable group. The primary purpose is to explain the nature of the relationship, not to determine the cause and effect. in terms of quantity hence; it is usually associated with values that can be counted such as age, weight, volume, and scale. the cohort population.

What is the difference between cohort study and case-control study? Hence, it is more suitable for research processes that examine, Qualitative observation gathers data samples using complete observer, observer as a participant, participant as an observer and complete participant methods while quantitative observation collects data samples using surveys, questionnaires, and polls. 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. Observational: As we mentioned earlier, longitudinal studies involve observing the research participants throughout the study and recording any changes in traits that you notice.

Unauthorized use of these marks is strictly prohibited. However, while qualitative observation draws data samples from actual interaction with the participants, quantitative research may utilize different indirect methods for data collection from participants. It is usually carried out with a large data sample size because the larger the research sample; the more accurate the research findings would be. Awareness of these approaches can help researchers construct their study and data collection methods. Researchers must consider their hypotheses and what forms of data collection and analysis are likely to produce the most relevant findings.
