Talk:Mean

From Wikipedia, the free encyclopedia

Just curious... Why not include the simple arithmetic process of finding the mean of a set of numbers? Some people don't understand Summation.

We already have a worked example for the arithmetic mean. I reverted your additions, for several reasons: First of all, you talk about two "methods" when in fact there is no principled difference between those "methods", it's just a difference in notation. Second, the bit about rounding the mean value to the nearest integer is just plain wrong: the mean age of a group is a well-defined concept. If you don't want a fractional answer, the concept you're looking for might be the median. --MarkSweep 05:45, 10 October 2005 (UTC)

There is a difference, Mark. I used the phrase "simple" arithmetic process. Someone may want to find the mean of a set of numbers, but if they do not understand Summation, then they do not understand the process used. Perhaps you could write out the process in summation so it would be easier. I know this site isn't a math lesson, but it would simply be helpful.

And if you have a number of people, you can't have eight tenths of a person, unless they are in a casket with no head. My reasoning for rounding is that having only part of a person is impossible. In other situations, such as classroom grades, having a mean of 75.8 would be totally reasonable. In the given situation, it was not.

I must respectfully disagree with your edit, but I will leave it.

[edit] can i know the reason

Hi,

Can I know the reason for revertig the link Dynamic arithmetic mean, median, mode calculator

Was it irrevlevant?

The calculator link did not strike me as particularly helpful, and the page has a lot of ads on it. --MarkSweep (call me collect) 06:22, 4 November 2005 (UTC)


Not helpfull??? Ok, I will not bother wiki with more links....

Better reason: the calculator is incorrect. For example, the median of the list (1,2,2,3,4,4,5) is 3. It isn't 4 as your link suggests. So thanks for not bothering us with more disreputable links. Silly rabbit 23:10, 23 November 2005 (UTC)

[edit] Relationship between different types of mean

I hase described these here:

http://en.wikipedia.org/wiki/Talk:Average#Relationship_between_different_types_of_mean

I would be very happy if someone could check them and add them to either article.

thanks.


[edit] Why isn't there something like "mean people" described here?

Why isn't there things about being mean described here? Definitions of it or so? Why keeping serious and adult and not think like a child? Anyway, maybe I might start it myself.


[edit] The Rational Mean

The Rational Mean is the unifying concept which embraces all known Means and the most simple principle for generating high-order root-solving methods, as shown at: The Rational Mean

So, it is disturbing to realize so many people seem unaware of this basic arithmetical principles and methods. —The preceding unsigned comment was added by [[User:{{{1}}}|{{{1}}}]] ([[User talk:{{{1}}}|talk]] • [[Special:Contributions/{{{1}}}|contribs]]).
