Your responsibilities include designing and executing the experimental approach. After completing thestudy, you realize that no control variables were defined. How will this impact your drug study?Answer:Failure to define the control variables implies that many unintended factors were left to change with theapplication of the drug. This would prevent you from determining whether any inhibition of thecancerous cells was due to drug X or some other factor that you did not control. The result is the studywould have to be repeated using appropriate controlled variables.15
