Answer 4

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

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

Answer 11

Why don't you enlighten me @amistre64?

Answer 12

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

Answer 13

i thought 92

Answer 14

am i wrong?

Answer 15

"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.

Answer 16

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

Answer 17

78 appears twice and 90 also appears twice

Answer 18

yeh...u r wrong

Answer 19

@cherry_pie what do you think is the mode?

Answer 20

oh i just noticed that lol

Answer 21

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

Answer 22

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!

Answer 23

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

Answer 24

trusted, your mode is wrong

Answer 25

this is bi-modal

Answer 26

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!"

Answer 27

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

Answer 28

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

Answer 29

amistre dats a lie

Answer 30

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

Answer 31

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

Answer 32

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

Answer 33

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

Answer 34

mode is not an average of modes ...

Answer 35

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

Answer 36

Answer 37

we are here to learn

Answer 38

http://www.purplemath.com/modules/meanmode.htm

mode = 78,90

Answer 39

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

Answer 40

@foolformath in that question i never typed the answer i just told what is the meaning of mean, median and mode you can see

Answer 41

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

Answer 42

kkkk

Answer 43

am i still a "liar" :)

Answer 44

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

Answer 45

@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
