An experiment is a process or study that results in the collection of data. experiments are not known in advance. control the factors that are irrelevant to the research objectives. car, speed, road surface, weather, and driver. Experimental design is the process of planning a study to meet specified objectives. Planning. an experiment properly is very important in order to ensure that the right type of data and a. sufficient sample size and power are available to answer the research questions of interest as. clearly and efficiently as possible.
Quasi-experimental designs identify a comparison group that is as similar as possible to the. treatment group in terms of baseline (pre-intervention) characteristics. There are different techniques for creating a valid comparison group such as regression. discontinuity design (RDD) and propensity score matching (PSM).
