A Correct answer
Explanation

Sort the observations: 3, 6, 10, 12, 16, 18. There are 6 observations (even number). The median is the average of the two middle terms (10 and 12). Median = (10+12)/2 = 11.

AI explanation

To find the median, first arrange the observations in ascending numerical order to get 3, 6, 10, 12, 16, 18. Since there is an even number of values, the median is the average of the two middle terms. Adding the two middle terms, 10 and 12, and dividing by 2 gives a median of 11.
