What is a Reliable Set Regarding % ?

WISE · 2014-03-14 02:09:35

A = 3 B = 7 C = 9

A = 30 B = 70 C = 90

The Problem with the above is that they all have the same % for each! as a Group

But the second line must be more reliable because there are more examples! So how do you tell the % function that! ?

How many do we need for any Example to be Reliable ?

A = ? B = ? C = ?

The Problem with the above is that they all have the same % for each! as a Group

Why is that a problem?

But the second line must be more reliable because there are more examples!

As they are they are just numbers. Do they represent something else? Are they a sample of something?

How many do we need for any Example to be Reliable ?

Need more explanation. describe the entire problem, leave nothing out.

Town 1 Vote A = 3 B = 7 C = 9

Town 2 Vote A = 30 B = 70 C = 90

Look at the above in a Voting way for something!

Example A there is a BIG! difference in 3 & 30 People from Town 1 & Town 2

bobbym · 2014-03-14 02:34:59

Why?

At present the only thing we have is that there is an election, three people ( I assume ) are running. A gets some votes, so does B and C gets the remainder of them.

So far, it does not look like there is anything to compute. What do you mean by reliable?

WISE · 2014-03-18 02:56:17

What I mean by reliable is ...

Better example

Town 1 Vote A = 3 B = 7 C = 9

Town 2 Vote A = 30 B = 70 C = 90

Town 3 Vote A = 3000 B = 7000 C = 9000

Looking at all the Vote examples for A from the 3 Towns 3,30,3000

Does every one think that the % examples for A is an example of something that is Fair & reliable ?

A Wins in every example and gets in ? but can a reliability factor be built in ?

What I mean is... Town 1 total = 19 Town 2 total = 190 Town 3 total = 19000

So the Pool of voters is much smaller in Town 1 compared to Town 3 ?

Can a minimum/maximum Pool of voters Etc.. be used as a reliability factor ?

Maybe knowing all of a countries average Town population's could be a way ?

We already have that by summing up all the votes.

But what we do not have is anything to determine. Since this is the result of one election, I do not see what there is to compute. Why is 3000, 7000, more reliable than 3,7? If something happened 3000 times in a row, then maybe we could talk some statistics. But this happened only once.

WISE · 2014-03-18 03:08:26

So if 3 People agree on something converted to 30% do you think it is equal in a reliable way as 3000 converted to 30% ?

bobbym · 2014-03-18 03:27:10

Hi;

So far, I have nothing to say about it at all. If two guys had an election and A got 4 votes and B got 6 votes compared to an election of 4000 and 6000, intuitively I would think the larger election was better because the winner won by 2000 votes! In the smaller election he won by only 2 votes. Even though the percentages are the same, intuitively it seems that the larger election is the more stable.

But intuition is often wrong when dealing with probability or statistics.

WISE · 2014-03-18 03:33:03

So I think you agree with me that many Math functions lie!

How can we rely on % being True ? % knows nothing about being reliable or as you say stable

There has to be a better way of calculating % ?

Agnishom · 2014-03-18 03:40:43

Hi;

What is reliability? I do not see anything wrong with the calculations

bobbym · 2014-03-18 03:42:39

So I think you agree with me that many Math functions lie!

If you were saying lots of physics or psychology or economics was kaboobly doo, I would be right in there with you blathering like mad but math is a lot more rigorous than those things.

Percentage is defined that way. We can not say it is wrong anymore than we can say that the rook in chess moves incorrectly. The rules of the game say that is how it moves and math too is a game. It can not be wrong in the sense you mean. We can be using it wrong, that is true.

WISE · 2014-03-18 03:47:00

More! is generally regarded as being reliable! but the % function as shown distorts this into a ?

Agnishom · 2014-03-18 03:52:15

In statistics, just one test is not reliable. You must look at the data in various ways to get an idea of what is going on.

Figures do not lie, but liars figure

bobbym · 2014-03-18 03:55:18

More! is generally regarded as being reliable! but the % function as shown distorts this

A larger sample size is more reliable but yours is not a sample it is the actual result

WISE · 2014-03-18 04:00:57

So what's your Verdict more is true ? or % is wrong ?

WISE · 2014-03-18 04:03:30

So if 2 actual results have the same % which is best ? 3 or 3000 both are equal to 30% and both are actual results!

Agnishom · 2014-03-18 04:03:54

bobbym,

Why is getting 3000 votes more stable? The probability that you get 3000 votes is the same as the probability you get 3 votes when the sample space is smaller

bobbym · 2014-03-18 04:06:10

We can not argue with the actual results. If I score 70% on a test by getting 7 out of 10 can you say that is incorrect?

So if 2 actual results have the same % which is best

Which is best? You need to define best.

WISE · 2014-03-18 04:11:45

Which is Best (3 that equals 30%) or (3000 that equals 30%) ?

bobbym · 2014-03-18 04:14:17

If you have 30 people in a room and you find that their average age is 34 and then you go to a stadium with 50000 people and get their average age of 34 why can you say one is more reliable or best. They are both exact answers.

Your original question was about an exact result not a poll.

WISE · 2014-03-18 04:16:37

Can you Define exact ?

bobbym · 2014-03-18 04:21:51

7 out of 10, is and always will be 70 percent.

The quality of a poll would depend on the size but the election itself is not a poll.

WISE · 2014-03-18 04:25:23

You started the word poll ?

What we want to know for sure is!... as an Example is any 30% of something!

as reliable as any other 30% of something ?

bobbym · 2014-03-18 04:32:18

You have not told me why you think my stadium example is incorrect.

bobbym · 2014-03-18 04:42:31

How can the two averages be different or more reliable. They are the exact answers! Both groups have an an average age of 34. No inference can be drawn. It is an exact calculation.

When you state that percentage is wrong and math lies then you are not correct.
