A scoring key was also prepared by the investigator to score responses on the master sheet. Weight age and the Range of Scores A weight age of one mark was assigned to each correct response and zero to each incorrect response. The minimum score in the test will be 0 and the maximum score in the test will be 40 as The Environmental Pollution Awareness Test consist of forty items so the scores for Environmental Pollution Awareness Test will be in between (0 to 40).
