The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.
LIMITATIONS:
<u>descriptive method of investigation
</u>
It cannot be used to correct variable or be used to determine causes and effect of the problem
<u>experimental method of investigation
</u>
It might create an artificial situation that do not always represent the real life situation
<u>comparative method of investigation
</u>
It is not easy to control other variables that might influence the study
