Research on learning applies various designs which refer to plans that outline how information is to be gathered for testing a hypothesis or theoretical assumption. Research designs are the heart of quantitative research. They include systematic observations, measures, treatments, their random assignment to groups, and time. Accordingly, research designs include identifying the data gathering method(s), the instruments to be used or created for assessment, how the instruments will be administered, and how the information will be organized and analyzed in accordance with the subject to be investigated. Among the various designs to consider in the area of research on learning are Show
Each design offers its particular advantages and disadvantages concerning validity, reliability, and feasibility. Although all experiments share common features, their applications vary in accordance with... This is a preview of subscription content, access via your institution.

As one example of a quasi-experimental study, a hospital introduces a new order-entry system and wishes to study the impact of this intervention on the number of medication-related adverse events before and after the intervention.
What is the difference between a quasiLike a true experiment, a quasi-experimental design aims to establish a cause-and-effect relationship between an independent and dependent variable. However, unlike a true experiment, a quasi-experiment does not rely on random assignment. Instead, subjects are assigned to groups based on non-random criteria.
What is an example of quasi independent?Physical height may be a quasi-independent variable where people are separated into groups of being very tall, or not. Eye color, hair color, native language, and other initial differences that participants arrive with and cannot be changed but are the focus of the research can be quasi-independent variables.
What are the five types of quasiThese are the posttest only design with nonequivalent groups, the pretest-posttest design with nonequivalent groups, the interrupted time-series design with nonequivalent groups, the pretest-posttest design with switching replication, and the switching replication with treatment removal design.
