Experimental design provides the greatest amount of control possible to examine causality more closely. Researchers may combine characteristics of more than one design to meet the needs of their study (Grove, S., Gray, J., Burns, N. (2015). An example of this in the healthcare studies is that they do a pre-test, post-test design with experimental groups. This is more tightly controlled in the areas of intervention, setting, measurement, and extraneous variable, resulting in fewer threats to design validity. Usually experimental design is done in a lab because it gives a high level of control and reliability.      Non-experimental design is weaker on with respect to internal validity or causal assessment. The simplest form of non-experiment is a one-shot survey design that consists of nothing but a single observation. This is probably one of the most common forms of research and, for some research questions especially descriptive ones is clearly a strong design (Trochim, 2006).  In other words it can be generalized to a larger population i need you to comment from this post 150 words needed and a reference please

The distinction between experimental and non-experimental design is critical in healthcare research. Experimental design is considered the gold standard in research as it provides the greatest amount of control to examine causality. The pre-test, post-test design with experimental groups is a commonly used experimental design in healthcare studies. This design helps reduce threats to design validity and increases control over the intervention, setting, measurement, and extraneous variables. On the other hand, non-experimental design is weaker in terms of internal validity or causal assessment. One of the simplest forms of non-experimental design is a one-shot survey, which is commonly used for descriptive research.

It is important to note that both experimental and non-experimental designs have their own strengths and weaknesses, and the choice of design depends on the research question and the goals of the study. Researchers should consider the trade-offs between internal validity, external validity, and practicality when choosing between experimental and non-experimental design.
