CFA一級數(shù)量分析考題也有概念基礎(chǔ)題也有計(jì)算題，今天我們看看CFA考試中的計(jì)算題，看看你數(shù)學(xué)學(xué)習(xí)的怎樣呢？

Given the following observations:2, 4, 5, 6, 7, 9, 10, 11 The 65th percentile is closest to:

A   5.85.

B   6.55.

C   8.70.

這就是今天小編給你看到額CFA一級數(shù)量分析的考試題，在CFA一級數(shù)量分析中也是有數(shù)學(xué)知識的，我們先看看這道題怎么解答吧！

答案【C 】With eight observations, the location of the 65th percentile is:

(8 + 1) × 65 / 100 = 5.85 observations

The fifth observation is 7 and the sixth observation is 9, so the value at 5.85 observations is： 7 + 0.85(9 – 7) = 8.7.


其中的核心詞匯Percentile：百分位數(shù)

是指將數(shù)據(jù)排序后平均分成100份，每一百分位所對應(yīng)的數(shù)據(jù)的值。
