An example problem:
When using the textbook formula, Median = L + {[(n/2)-c.f.]/f}*h, where L is the lower limit of the median class, n is the total number of observations, c.f. is the cumulative frequency of the class preceding the median class, f is the frequency of the median class, and h is the class width.
In the example problem, what class shall be taken as the median class 30-40 or 40-50, since n=50. Does the 25th observation lie in the 30-40 class or 40-50 class?
Note: I understand that this may seem like a textbook question, but I assure you my peers and teachers are having mixed answers. I have searched Google and have also found mixed answers either saying that: 1. the median class contains the median, thus 30-40 is the median class, 2. when finding medians, we follow the exclusive model thus, 40-50 is the median class. Anything helps, even a link to a similar question if this is a duplicate.
