if data is collected during a drug trial testing antibiotics on methicillin resistance bacteria, we have different doses in one side( .50, 1. 1.5), and percent of inhibition of bacteria ( antibiotics daptomycin, linezolid, dalfopristin) on the other side. what is the dependent variable and what are the independent variable? and draw graph. if any one who knows the answer let me know.

+Hena Rahman A control is set up to show that the results that you get are due to what you have tested for, and no other factor is influencing your results. For example, if you want to test whether carbon dioxide is necessary for photosynthesis - the experiment would be to use soda lime to remove the carbon dioxide, whilst your control would be setting up the exact same same conditions, but without the soda lime.
