Which one of the following is the best example of action research? Question options: A) A college professor recruits sixth graders to come to his lab, where she assesses their responses and reaction times in a variety of challenging problem-solving tasks. Her results will help her refine the theory of problem solving she has been developing. B) A graduate student quietly observes adolescents' behaviors in the school cafeteria. He plans to describe his observations in his master's thesis. C) A teacher gives her students a questionnaire that asks them to describe how often they study and what kinds of strategies they use when they study. She will use the results to develop several lessons on effective study skills. D) All of the school districts in a particular state are instructed to give the same mathematics achievement test to their high school juniors. The average test scores for each district will be presented in a report that will be released to the general public.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
