計劃進修PhD/Research討論區 (10) 學而不思則罔，思而不學則殆

呢個問題存在好耐
open database 係解決之道

呢個情況其實似你普通run individual data時
你放兩組15+15人時唔sig, 放30+30時可能sig, 每個人自己baseline posttest比可能唔食

一切係effect size and power既問題

如果你唔放non sig data, 一來係publication bias selection bias,
二來驗證唔到個effect size係因為power定其他

當然，如果你越放得多越heterogeneous, 咁代表不同paper variety 高

講到尾，meta analysis都只不過係一種estimation，我唔明點解咁多人覺得佢好神

是咪都係要考final個類

我果時果個得midterm+present 唔少pg course都要你做present架啦對教果個prof都叫可以慳返時間睇paper
