  1. Looks good!
    1. RCI 數據小數1位即可。
    2. Cohen's d 數值有誤,請修改。
    3. 增加計算 overall (4 assessments) ICC
    4. 增加計算 4 assessments 之 trend (repeated-measures ANOVA) 是否顯著,亦可繪圖呈現。
    5. 有明確的 p value 即毋須顯示 "**Significant: p value < 0.05" 因為畫蛇添足。
    6. range 的小數點,與其它數據需一致(小數1位)。
    7. ICC 請增加 95% CI
    8. 請增加 Table 之標題
    9. 修改後,請找我討論。

  2. 1,2,5,6,8:已修改,且張貼於9/5部落格"Test-retest reliability and practice of FDT"。
    3,7:已張貼於9/5部落格"四項電腦之ICC"。
    4:已張貼於9/5部落格,"SAT之ANOVA結果"、"PDT之ANOVA結果"、"FDT之ANOVA結果"、"WCST之ANOVA結果"。

  3. 謝謝老師的指正。
    我第3題做錯了,我應該要做FDT之4次測驗的ICC值。
    第4題的所畫的圖,scale所取的值都太小,以致線段下降和上升變得太誇張,這樣會誇大practice effect太明顯。所以我所剛剛畫的圖都是不精準。

  4. 第3題的修改,張貼於9/5部落格"FDT:4次測量之ICC"。
    第4題的修改,張貼於9/5部落格"FDT:4次測量之boxplot"。
