@amistre64: Check her recent questions. I was trying to help her when someone else drop in the answer and she left.

@cherry_pie you have done well with the first two. What's mode?
amistre64
  • amistre64
im well aware of that, but that does not excuse your conduct. There are simply nicer ways to present it. imo
anonymous
  • anonymous
mode is that number which repeats highest number of times in the series
anonymous
  • anonymous
this is really annoying if i got the answer wrong can you show me how you got the right answer

@cherry_pie which test score appears the most no. of times?

"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
ash2326
  • ash2326
78 appears twice and 90 also appears twice
anonymous
  • anonymous
yeh...u r wrong
ash2326
  • ash2326
@cherry_pie what do you think is the mode?
anonymous
  • anonymous
oh i just noticed that lol
anonymous
  • anonymous
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
amistre64
  • amistre64
trusted, your mode is wrong
amistre64
  • amistre64
this is bi-modal

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!"

Trusted, do you want to throw accusations with no proof about? or do you want to back up your answer?

mi bad....82+90/2=86...
amistre64
  • amistre64
that good for the median yes; what about the mode?
anonymous
  • anonymous
mode is 78+90/2...78 n 90 appear twice.....168/2=84
amistre64
  • amistre64
mode is not an average of modes ... http://www.wolframalpha.com/input/?i=mode&a=*C.mode-_*MathWorld-
amistre64
  • amistre64
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
anonymous
  • anonymous
so wats he solution
anonymous
  • anonymous
we are here to learn
amistre64
  • amistre64
http://www.purplemath.com/modules/meanmode.htm its the set of the numbers used the same number of times ... mode = 78,90

@foolformath in that question i never typed the answer i just told what is the meaning of mean, median and mode you can see
amistre64
  • amistre64
unless of course all the numbers are used once, then its simply no mode ... which seems confusing to me
anonymous
  • anonymous

am i still a "liar" :)
anonymous
  • anonymous
m not here to fight i have got certain good friends here so m in no mood to spoil it so @foolformath i m no mood to lose some good friends over this small issue so i will do one thing if u feel i was wrong its ok and i accept it m sorry for it right now are you happy
anonymous
  • anonymous
@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 :)
