The correlation coefficient model for evaluating the university physical education teaching technique with dual hesitant fuzzy information

摘要

In this paper, we investigate the problems for evaluating the physical education teaching technique in universities with dual hesitant fuzzy information. Then, we compute the correlation coefficient between each alternative and positive ideal alternative, and then rank the alternatives by means of the correlation coefficient between each alternative and positive ideal alternative. Finally, we shall present a numerical example for evaluating the physical education teaching technique in universities with dual hesitant fuzzy information in order to illustrate the method proposed in this paper.
