日本における統計改革 : 基礎心理学研究を資料として

抄録

In the late 1990s, the American Psychological Association advocated improved statistical practices, including reporting confidence intervals (CIs) and effect sizes. Since this statistical reform, the numbers of reports in international academic journals of psychology which have included the CI and effect sizes have increased. We investigated the evidence for statistical reform in Japan by examining papers published from 1982 to 2008 in the Japanese Journal of Psychonomic Science. The reports which included CIs and effect sizes were extremely rare in the journal even after 2001. This observation suggests that this statistical reform has not yet started among Japanese researchers in psychology.
