    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:

    \text{Mean } = \frac {13 + 13 + 15 + 15 + x}5 = 15

    now solve for x


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