Quantitative designs can be experimental, quasi-experimental, descriptive, or correlational. Quantitative studies can be quickly produced with the benefit of data computing software. In retrospective studies, individuals are sampled and information is collected about their past. Quantitative research is characterized by collecting quantifiable metrics and conducting statistical, mathematical, or computational techniques as a systematic analysis of phenomena. Retrospective study designs are generally considered inferior to prospective study designs. In some cases, the researchers can spend years documenting the changes among the variables plus their relationships. Quantitative observation produces bias-free outcomes because this method of investigation adopts definite and objective approaches to the examination of research variables. quasi-experimental). A quantitative observation is an objective method of data analysis that measures research variables using numerical and statistical parameters. While the former is used for research analysis aimed at describing the nature of the variables, the latter is used to quantify variables based on numerical values.
