In a recent study, the returns of a certain investment portfolio over the last 5 years were recorded as follows: 8%, 11%, 7%, 10%, and 14%. An analyst is trying to evaluate the central tendency of these returns to assess the portfolio's performance. Which of the following options correctly identifies the median return of this investment portfolio?
To calculate the median, the analyst must first arrange the returns in ascending order. The ordered returns are: 7%, 8%, 10%, 11%, and 14%. The median is defined as the middle value in a dataset. In cases where the number of observations is odd, the median is simply the value in the center. If the number of observations is even, it is calculated as the average of the two middle values.
