As per (2017). experimental research is done in a lab and is able to manipulate the predictor variable and subjects to identify a cause and effect relationship.  An example of experimental research is done with two groups an experiment group and a placebo group which has high level of control and variability.  With experimental research the variable has to be able to change.  Gender cannot be a variable with experimental research.

Non experimental research cannot control, manipulate or alter the predictive variable or subjects.  It relies on observation, interpretation or interaction to come to a conclusion.  This means non experimental research relies on surveys, correlation and case studies.  An example of non experimental research is the question how compassionate are men and women?  Gender cannot be used in experimental research.  In experimental research there is a high level of control and in non experimental research there is a low level of control but you can have a larger amount in the study compared to experimental. Non experimental research has a lot of disadvantages.  It cannot find a cause an effect relationship and cannot manipulate predictor variables (Burns, et al, 2015).  It’s important to know the difference between experimental and non experimental research.
