The Soloman Four Group Design is a research method that is sometimes used in social science, psychology and medicine. It can be used if there are concerns that the treatment might be sensitized by the pre-test.〔Introduction to Research in Education by Donald Ary, Lucy Jacobs, Christine Sorensen〕 The four groups have four different experiences: # Pre-test, treatment, post-test # Pre-test, no treatment, post-test # Treatment, post-test # No treatment, post-test The effectiveness of the treatment can be evaluated by comparisons between groups 1 and 2 and between groups 3 and 4. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Soloman Four Group Design」の詳細全文を読む スポンサード リンク
