Explanation : The mode is the most frequent value in the set of items and thus is equal
to 41. The mean is the average value from the set of items and is
computed as follows:
Mean = Sum of observations / Number of observations = 456 / 10 = 45.6
The median is the value of the middle item of a set of items. For even
number of observations, the median is equal to the average of the
middle two values. The median is thus the average of 41 and 43. Median
= 42. Therefore, the median is smaller than the mean but larger than
Explanation : Add one to each of the given returns, then multiply them together, then
take the fifth root of the resulting product. 1.18 × 1.12 × 0.95 × 0.90 ×
1.07 = 1.209066. 1.209066 raised to the 0.20 power is 1.0387.
Subtracting one and multiplying by 100 gives the correct geometric
mean return of 3.87%.
