113學年臺灣大學心理系轉學考 - 普通心理學(14)

更新 發佈閱讀 2 分鐘
A test is valid if
(A) It is correlated with psychologically interesting measures.
(B) It is consistent.
(C) the same score would be obtained if the same person took it twice.
(D) it measures what it claims to measure.
一份測驗是有效的當
(A) 它與心理學上有意義的測量相關
(B) 它有一致性
(C) 相同的人做兩次測驗都獲得相同的成績
(D) 它可以測量的到它宣稱所要測量的東西

一份測驗要有信度(reliability)和效度(validity),信度是指不管何時測驗一致性都很高,效度則是強調是否能有效測出我想要測量到的東西。若沒有信度,就一定沒有效度。

選項(A)不能選的原因是因為這份測驗不一定跟心理學上其他測量有相關,例如你想要測量智力,卻拿焦慮量表做相關的比較。
