Do round numbers always become reference points?: An examination by Japanese and Major League Baseball data
- Kuninori Nakamura, Faculty of Social Innovation Seijo, Setagayaku, Japan
AbstractThe round number effect refers to discontinuity around round numbers (“0.300”, “4 hours”) in frequency distribution, indicating that people consider the round numbers as goals or reference points for their performances. This study aimed to examine the round number effect by exploring the following two issues: (1) examination of Japanese baseball data, and (2) comparison between batters who exceeded the regulation number of at-bat of season and those who did not. Results indicate the following three points; (1) the round number effect was found in Japanese baseball data, (2) but it was found only for the batters who exceeded provision bat number of season, and (3) magnitude of the effect was stronger in Japanese than Major League Baseball data. General discussion argued these results in terms of players’ motivation and disposition.
