Out of 11 bihs in a hospital, 5 babies weighed over 2.5 kg and 5 weighed less than 2.5 kg. What value does 2.5 represent:
Correct Answer: Median average
Description: The 'median' refers to the value of the middle observation, when data is arranged in an ascending or descending order of magnitude. In the given question, 5 values are greater then '2.5' and 5 values are less than '2.5'. Thus, 2.5 is the middle value of this set of data and stands for the median.
