I heard median of any number of data. Suppose we have a data
[13,23,23,23,54]
The median of this data is is 23.
How we calculate the weighted median of same data (as mentioned above).

** http://en.wikipedia.org/wiki/Weighted_median (this is i get when i Google it. But things are not clear).

If you have your five data the median is just the value appearing in the third position. Now, assume you have

dataweight1310233544
where the weight is the number of times that a given data appears. Now, you have 17 data. The weighted median is the value in 9th position, that is, 13.

In fact, when you compute the median with your data you are actually working with a weighted data

dataweight131233541

  • I think it is important to note that data should be ordered in order to find the median. In this particular case, the median of the set of 5 data is just the value appearing in the third position because the data are already ordered. It is also important to note that the list of weighted values has a one-to-one correspondence with the list of data entries.
