The variables are measured, and then statistical analyses are conducted to test for a relationship among the variables. The DV is the variable that is being observed and measured. When research is found to be reliable, then it is thought that the research findings are representative of the population and can be applied to real-life settings.

Due to its availability, functional magnetic resonance imaging (fMRI) is widely used for this purpose; on the other hand, the demanding cost and maintenance limit the use of magnetoencephalography (MEG), despite several studies When the data is monitored and administered efficiently, then only the true effects of data validation would be extracted out. With experimental testing individual experiments have to be done in order to fully research each variable. 5.
