1. Which of the following is(are) example(s) of an experimental research? A study took a random sample of adults and asked them about their morning routines. The data showed that adults who do not use theirmobile devices for more than ten minutes immediately, after waking up are more likely to have a more productive morning 1. than those who do. To evaluate the four most popular productivity techniques, researchers randomly assigned students into four groups; each group was assigned to strictly follow one of the four productivity techniques for the entire school term. The grades of the students were compared after. I. A. I only B. Il only C. Both I and II D.
