Explanation:

Causal analysis, also termed causal analysis, is the study of the links between causes and effects. In order to identify causal link, it is necessary to identify differences in the variables that are believed to trigger the shift in another variables and then calculate the differences in the other.

This form of study is very complicated and the investigator could never be entirely confident that there are hardly any other variables affecting the causal link, particularly when working with the perceptions and motives of individuals. There are also psychological factors far deeper than even the participant might not be conscious of.
