Detailed explanation-1: -Hence, the Absence of a treatment group is a process not needed in experimental research.

Detailed explanation-3: -Solution(By Examveda Team) The process not needed in experimental research is reference collection.
Detailed explanation-4: -Experimental manipulation describes the process by which researchers purposefully change, alter, or influence the independent variables (IVs), which are also called treatment variables or factors, in an experimental research design.
Detailed explanation-5: -Therefore, in experiments, a researcher manipulates an independent variable to determine if it causes a change in the dependent variable. As we learned earlier in a descriptive study, variables are not manipulated. They are observed as they naturally occur and then associations between variables are studied.
