    im well aware of that, but that does not excuse your conduct. There are simply nicer ways to present it. imo

    mode is that number which repeats highest number of times in the series

    "Please nobody give her the answer." Regardless of what you meant by this, it comes across as harsh; and with your title of moderator, it leads to a sense of a demand rather than advice to me.

    @Cherry_pie first thing that you have to do is to arrange the series in ascending order

    90, 82, 78, 78, 90, 92 in ascending order it can be written as 78, 78, 82, 90, 90, 92

    Regarding my earlier comment: Here: http://openstudy.com/users/cherry_pie#/updates/4fa00de4e4b029e9dc310b84 The user claim to be have understanding of mode, "mode-is the one that appear more often" but still she was having trouble in understanding the meaning. I was trying to help her but suddenly the user @sheg dropped in the answer and she left. I don't know about anybody else but it's tad annoying. Hence, I said "Please nobody give her the answer". Hope this clarifies everything!

    median is 86 mode (78+90)/2=84 mean=(78+78+82+90+90+92)/6

    Although, it wasn't something meant to be interpreted in a harsh way but the above behavior demonstrated by sheg is a violation of our CoC: This is direct violation of code of conduct "Don't just provide the answer to a problem when someone else is in the middle of helping!"

    mode is not an average of modes ... http://www.wolframalpha.com/input/?i=mode&a=*C.mode-_*MathWorld-

    if 2 or more amounts are used the same number of times; the mode is defined as the set of them, and not the average of them

    unless of course all the numbers are used once, then its simply no mode ... which seems confusing to me

    @sheg: From your answer: "we are having 7 terms so median is the4th term i.e., 84" "Mode is that term which repeats highest number of times and in this series it is 86" I am sure that you are aware of the fact that your answer doesn't help OP to understand the concept as that entails this question and her next question : http://openstudy.com/users/cherry_pie#/updates/4fa01274e4b029e9dc3111b9 :)
