Each research design has its uses and points of strength and limitations. If you want to have first-hand, factual information about the changes in a sample population, then you should opt for a panel study. Longitudinal studies help you discover variable patterns over time, leading to more precise causal relationships and research outcomes. In qualitative observation, the researcher does not work with any fixed parameters in generating research outcomes rather, s/he collects and describes a variety of information related to the research variables. A quantitative observation is an objective method of data analysis that measures research variables using numerical and statistical parameters.

For example, when a researcher pays equates research variables in terms of their quality, then this is qualitative observation. Quantitative observation produces bias-free outcomes because this method of investigation adopts definite and objective approaches to the examination of research variables. Quantitative observation defines research data based in terms of quantity hence, it utilizes statistical parameters for measurements. Due to the length of the research process, some variables might be unable to complete the study for one reason or the other. Studies with the highest internal validity, characterized by a high degree of quantitative analysis, review, analysis, and stringent scientific methodoloy, are at the top of the pyramid.
