Sadara would like to know the course preference of Senior High Students in a certain school by using a sample of Grade 11 and Grade 12 students. In her study, she utilized all honor students to rank all the courses with 1st being the course they like the most and 10th being the course they dislike the most. Then, in the summary of the results of her study, she calculated the mean of the ranks in each course to determine which courses are the top three most preferred and the three most disliked courses. The results showed that senior high students' three most liked courses are Personal Development, UCSP, and Chemistry/Marketing while the three most disliked courses are General Mathematics, Qualitative Research, and Philosophy. Sadara concluded from the results that maybe students disliked Philosophy and General Mathematics due to the pureness and the difficulty of the courses and liked Personal Development and UCSP due to the relevance ofthe courses. The following are the errors committed by Sadara in her study EXCEPT one. Which of the following is not an error of the study? A. Choosing only the honor students in the study, which signifies a non-random sampling procedure was used. B. Getting the mean of ranks to describe the top liked and disliked courses. C. Selecting only the top three liked or disliked courses from the list. D. Formulating conclusions or inferences on the reasons of the top three liked or disliked courses based on the ranks.
