Your responsibilities include designing and executing the experimentalapproach. After completing the study, you realize that no control variables were defined. Howwill this impact your drug study?Answer: Failure to define the control variables implies that many unintended factors were left tochange with the application of the drug. This would prevent you from determining whether anyinhibition of the cancerous cells was due to drug X or some other factor that you did not control.The result is the study would have to be repeated using appropriate controlled variables.Topic: Sec. 1.3Bloom's: Evaluating/CreatingLO: 1.3GLO: G8
