You go ahead to recruit a set of newly-born lion cubs and study how they relate with each other as they grow. Qualitative observation is usually conducted on a small data sample size while quantitative observation is carried out on a large data sample size. Qualitative observation, on the other hand, uses inductive analysis and naturalism to describe the nature of research variables. It is used for examining phenomena expected to remain static through the period of interest. 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. Is a manipulated study an experiment or observational study? A cross-sectional study is a type of observational study in which the researcher collects data from variables at a specific moment to establish a relationship among them. As a result of its dependence on.
