A quantitative observation is objective while qualitative observation is subjective. Qualitative observation methods do not have fixed parameters for the examination of sample data instead, these methods are modified based on the discretion of the researcher to suit the sample and research environment. Because longitudinal studies span over a more extended time, they typically cost more money than cross-sectional observations. Ultimately, the researcher must determine which kind of research best serves the goals of the study.
