【Answer to question 1】C
【analysis】
C is correct. The geometric mean annual return is computed multiplicatively as the nth root of the holding period.
【Answer to question 2】C
【analysis】
C is correct. The sample variance is calculated as the sum of squared deviations from the arithmetic mean.
A is incorrect. This is the calculation for population variance, which differs from the calculation for sample variance by the use of N in the denominator.
B is incorrect. The correct calculation requires subtraction of the mean before the values are squared and summed. This calculation is the sum of squares of the returns, not of the deviations.
成功=時間+方法，自制力是這個等式的保障。世上無天才，高手都是來自刻苦的練習。而人們經常只看到“牛人”閃耀的成績，其成績背后無比寂寞的勤奮。小編相信，每天都在勤奮練習，即使是一點點的進步，大家一定可以成為人人稱贊的“牛人”。更多CFA考試資訊，點擊了解>
