Question

Quizplus · Accepted Answer

The median is the middle value of an ordered data set. In this case, there are 30 items so the median would be the (30+1)/2 = 15.5th value. Since we cannot have a fractional observation, we take the average of the 15th and 16th observations, which are the 15^th and the 16^th observations. Therefore, the statement is true.
