In order to analyze the student's hypothesis testing ability, the following survey was carried out. The survey asked the following questions: (1) Are there differences in performance of hypothesis testing task among students' majors? (2) How does the student interpret the hypothesized relations between variables? (3) Whether do hypothesis testing ability and conditional reasoning ability exhibit a unidimensional scale or not? Method: evaluation Four selection hypothesis conditional reasoning task testing tasks and one were administered to undergraduate students. 185 students comprised the sample. The sample consisted of eleven majors. Results: The results of the present survey are summarized as follows: (1) There are no differences in performance of hypothesis testing task among students' majors. (2) About 50-55% of the students interpret the hypothesized relations between variables as biconditional. (3) Hypothesis testing ability and conditional reasoning ability don't exhibit a unidimensional scale.
