This research is included in the experimental design by using a mixed design of between-subjects and within-subject design and classified as experimental research which uses the 2x2x2 method. Participants used in this research are undergraduate business students in STIE Perbanas Surabaya who are studying and/or have completed investment management and/or financial statement analysis courses who will serve as non-professional investors.
