for the record, you should respond to my posts here.

now since you know the definitions, i don't suppose any of this will come as a surprise to you

so lets do this.

lets make up some data, for simplicity, we will take 5 values. i will write our values in ascending order, and an unknown x

13, 13, 15, 15, x

now we want:



now solve for x


can you see why i choose the data like that? do you see why it works?
