experiment relation with "research"

Experimental Research :
 A researcher working within this methodology creates an environment in which to observe and interpret the results of a research question. A key element in experimental research is that participants in a study are randomly assigned to groups. In an attempt to create a causal model (i.e., to discover the causal origin of a particular phenomenon), groups are treated differently and measurements are conducted to determine if different treatments appear to lead to different effects.


 Generalizabiltity:


The extent to which research findings and conclusions from a study conducted on a sample population can be applied to the population at large.
