題目說:
Let P denote the prevalence of a disease in a population and Px the proportion of positives in a screening of that population. Suppose that the screening method's sensitivity and specificity are both 95%. Calculate Px/P for different value of P. Draw a diagram to illustrate the relation.
我翻譯為:
P是人口當中罹患疾病的盛行率.Px是人口當中篩選出來是陽性的比例.假設精確度.敏感度都是95%.""計算Px/P對P.""畫圖並詳述.
我不太懂Calculate Px/P for different value of P.翻譯起來是什麼意思??
可不可以請董的人幫我解釋一下.
他的答案是一張圖表.可是我看不懂的的意思是什麼!?
可不可以請會的人幫我解答.並告訴我為什麼!
謝謝~
感激不盡~>"<
