PASS分析後 結果整理 (discharge score)

用discharge樣本，不刪題

person reliability = 0.91
person separation = 3.18

(依據Wright, B. D的說法，Low person separation (< 2, person reliability < 0.8 )with a relevant person sample implies that the instrument may not be not sensitive enough to distinguish between high and low performers. More items may be needed.所以目前的PASS是具有足夠item的)

刪去OUT_PASS07

person reliability = 0.91
person separation = 3.13

刪去OUT_PASS01

person reliability = 0.91
person separation = 3.10
