i got mean-85 median-78 mode-92

- anonymous

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

- anonymous

you weren't helping you were being annoying at least they showed me how they got the answer

- ash2326

@cherry_pie you have done well with the first two. What's mode?

- amistre64

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

- anonymous

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

- anonymous

this is really annoying if i got the answer wrong can you show me how you got the right answer

- anonymous

Why don't you enlighten me @amistre64?

- ash2326

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

- anonymous

i thought 92

- anonymous

am i wrong?

- amistre64

"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.

- anonymous

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

- ash2326

78 appears twice and 90 also appears twice

- anonymous

yeh...u r wrong

- ash2326

@cherry_pie what do you think is the mode?

- anonymous

oh i just noticed that lol

- anonymous

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

- anonymous

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

trusted, your mode is wrong

- amistre64

this is bi-modal

- anonymous

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!"

- anonymous

So, all I wanted is to make sure this doesn't happen again.

- amistre64

Fool, itll be ok :) and im pretty sure it will happen again :P

- anonymous

amistre dats a lie

- amistre64

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

- anonymous

mi bad....82+90/2=86...

- amistre64

that good for the median yes; what about the mode?

- anonymous

mode is 78+90/2...78 n 90 appear twice.....168/2=84

- amistre64

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

- 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

so wats he solution

- anonymous

we are here to learn

- amistre64

http://www.purplemath.com/modules/meanmode.htm
its the set of the numbers used the same number of times ...
mode = 78,90

- anonymous

Next time I am going to wear my moderators cap ;)

- anonymous

@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

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

- anonymous

kkkk

- amistre64

am i still a "liar" :)

- 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

@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
:)

- anonymous
