The median formula is used to

• A. The formula used to find the observation, or location, of the median in ordered data
• B. The sum divided by n
• C. The maximum value
• D. The standard deviation

Answer: (A)

Locating the middle value in a sorted data set is what the median tells us. The “median formula” gives the position of that middle observation in the ordered list: when there are an odd number of observations, it’s the (n+1)/2-th item; when even, the middle lies between positions n/2 and n/2+1 (often taken as the average of those two values). So this formula is about where the median sits in the ordered data, not about calculating a value from sums or dispersion.

This differs from the other options: the sum divided by n gives the mean, the maximum is the largest data point, and the standard deviation measures how spread out the data are around the center.
