Question

5. A shopping mall wanted to determine whether the more expensive

"Tough Stuff" floor wax was better than the cheaper "Steel Seal" floor wax


at protecting its floor tiles against scratches. One liter of each brand of


floor wax was applied to test sections of the main hall of the mall. The test


sections were all the same size and were covered with the same kind of


tiles. After 3 weeks, the number of scratches in each of the test sections


was counted to observe the wax's effectiveness. Identify Control Group

Answer 1

Control group:

Test section covered with the "Steel Seal" floor wax

Step-by-step explanation:

In a scientific experiment, the control group is the standard group to which comparison is made, to determine the effect of the experimental agent on the test subjects. In this example, the Steal Seal floor wax is the standard wax being used, and the experimenter wants to see if the "Tough Stuff" wax is better, hence after the treatment with the Tough Stuff wax, the number of scratches observed is compared with the standard wax area and the difference determines if it is a better waxing agent or not.
