As a research design, qualitative observation is used to gather information for policy formulation, developing new concepts and creating new products while quantitative observation is mostly used in scientific research since it generates numerically observed outcomes that can be measured. 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.
