2. amistre64

Fool, lets not pass judgement in that manner please

3. cherry_pie

look i'm trying what is your problem?

4. cherry_pie

i got mean-85 median-78 mode-92

5. FoolForMath

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

6. cherry_pie

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

7. ash2326

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

8. amistre64

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

9. sheg

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

10. cherry_pie

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

11. FoolForMath

Why don't you enlighten me @amistre64?

12. ash2326

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

13. cherry_pie

i thought 92

14. cherry_pie

am i wrong?

15. 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.

16. sheg

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

17. ash2326

78 appears twice and 90 also appears twice

18. Trustted

yeh...u r wrong

19. ash2326

@cherry_pie what do you think is the mode?

20. cherry_pie

oh i just noticed that lol

21. sheg

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

22. FoolForMath

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!

23. Trustted

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

24. amistre64

25. amistre64

this is bi-modal

26. FoolForMath

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!"

27. FoolForMath

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

28. amistre64

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

29. Trustted

amistre dats a lie

30. amistre64

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

31. Trustted

32. amistre64

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

33. Trustted

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

34. amistre64

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

35. 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

36. Trustted

so wats he solution

37. Trustted

we are here to learn

38. amistre64

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

39. FoolForMath

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

40. sheg

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

41. amistre64

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

42. Trustted

kkkk

43. amistre64

am i still a "liar" :)

44. sheg

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

45. FoolForMath

@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 :)
