doing project about anti-malarial drugs
I used malaria med tool to preform 3 tests using 3 typed of
drugs A.B and C ..all drugs are small size dose and used for
7 days . ..
important notice : in the 3 experiments
we changed only type of the drug , and kept
the dose small and 7 days the same for each test . the
result showed high drug resistant and different cost and side
effects. so we have 3 variables : drug type- drug dose size- number
of days.
1 .which one is control variable .
2.which one is independent variable.
3. which one dependent variable
