You a right on that but my point is I don't think we will ever see a 10 avg. and I don't think we will ever see a 0 avg. But if we did see them we have no problem knowing the picture that scored a 10 would win the blue. But were would the 0 avg. photo place? last? |
You will never see a 0 average here because 0 means that person did not tally a vote. They do not exist.
A 10 would be possible because the 10 voter does exist and is tallied.
What may be of interest is let's say 2 photos are entered ..no others.
The first photo gets a 10 from the single, lone voter interested in this pitiful 2 photo contest.
The second photo gets nothing. Not even a 0 cause we don't count 0's.
The first photo wins by default and averages his 10 score into his overall photo entry scores average ( 10 with only one vote counting as much as those 6's and sevens with hundreds of votes) but the second person's photo does not average into their total photo contest entry average because...just like a DQ..it has no mumerical value.

My point is we have a 1-10 scale and it is just as possible or close, to receive a Zero as a ten in overall voting. Out of a 100 votes it is very unlikely anyone will receive a 100 tens (perfect score) and it is very unlikely anyone will not get any votes but the possibilities are there.
If someone entered a picture and it received zero votes - how would it be scored? What place would it be in? |
If an entry did not receive any votes it would not have an average vote. We have been talking of averages in this thread. Non-votes are not included in the averages.
If you really think it is nearly as likely to receive a vote of zero as it is to receive a vote of ten, I have this really nice bridge that I am trying to sell at a bargain price. You would feel great as a bridge owner. |
not a single 10 or 0 vote but an avg 10 vote on no votes. I'm saying 10 votes averaging 10 is about as likely as no one voting on a picture.
And if that did happen, where would it place? It wouldn't be DQ'ed for not receiving any votes would it? so I has to place some where. |

Someone better-versed in statistics than I should wade in here and discuss the differences between "average" score, "median" score and "mean" score. I'll take a primitve stab at it.
What most of us think of as the "average score" in a given challenge is more properly called the "mean" (or "arithmetic mean") score; the total of all votes divided by the number of votes. It will vary from challenge to challenge. The figures quoted earlier describe the "mean" score of all challenges taken as a group, and are derived by calculating the means for each individual challenge. Except that the earlier-described "midrange" score (in any given challenge) is the calculated score that is halfway between the highest-awarded total score and the lowest-awarded total score for that challenge.
Mean is one kind of average. It is computed by summing the values and dividing by the number of values. Two other common forms of averages are the mode and the median. The mode is the frequently occurring value in a set. The median is the middle value of the set when they are ordered by rank.
I donno, I'm getting confused. This is not my strong suit. Soldier on in complete disregard :-)

Getting a perfect 10 is not likely but not impossible because the number 10 does exist in the DPC universe of numbers.
Getting a perfect 0 is impossible because 0 does not exist in our number system. Now, getting a photo with no votes is possible just like the perfect 10..BUT..that is not the same as getting a 0.
(If any body is confused yet, you may go to the bathroom or switch channels to the morality thread :-D )
I guess no one has addressed the "No Vote" scenario because the likelyhood of getting no votes IS as likely as getting a perfect 10.
My guess is that photo would be listed last..(unless lightning struck twice and more than 1 photo received no votes) Then..Just like DQ's..no place is assigned at all and no scores are recorded.

I was really getting the value of 10 and 1 =5.5
but the over all average of the site is not this.
No confusion just the highest score image is not over a 9
So if 9 was high, the average would be be 4.5? |

Lets back track for a moment. I'm not saying 0 is in our scale of voting, we all know that. But my question is hypothetical in nature seeing that a picture would score a 10 is about as likely as seeing a picture score a 0. But both are possible.
My questions are:
1. If a picture was entered in a challenge and received not votes where would it place in the challenge? I don't think DPC would DQ the image.
2. I would count as a challenge entry. So if someone had a 5.0000 avg on 50 challenges before there entry that scored a 0 or better said received no votes. Now they have 51 entries, wouldn't it effect there overall score? |

No, they are not both possible. It is not possible for anyone to vote a zero, therefore it is impossible for an entry to receive a score of zero. If an entry got no votes it would not be getting a score of zero. It would be receiveing no score at all, which is not the same thing as receiving a score of zero.

OK I'm through with the hypothetical thinking or debating :)
I was just wondering where would it be placed on the results page. We know if you add a score of 0 (or better said - receive no votes) to your avg at the same time you add votes of 0, it would not effect your overall score at all. You would just have one more challenge entry and your overall score would be the same.
It will never happen anyway.
Thanks for the debate

1+2+3+4+5+6+7+8+9+10=55
55/10 = 5.5
So if you received the full range of votes, equally spread, 5.5 would be the average vote.

1+10 (2 votes) = 11 / 2 = 5.5
2+9=11
3+8=11
4+7=11
5+6=11

can't say about others, my average vote recieved is around 4.5 and i am not a good photographer (this is a fact).

I have seen threads talking about the average is 5.5, what a load crap.
Does not compute. No image has ever scored a 9 at the end. Wonder what the DPC average vote is? If you over all average is 4.5, does this make you bad photograph?
Where is the stat man at? |

What's the point of this conversation anyways?
Just wondering...

One point, one question:
Point: To make the 0-score more intuitive, ask yourself if it's possible to get a score of 0.5000 (or anything between 0 and 1). It isn't. So a score of "zero" makes no sense.
Question: Can someone rerun those stats for only 2005 and 2004 put together? I think the average is a moving target and things have changed since the conception of this site. The early challenges may be tainting the numbers and I'm curious as to how much. |

Already have but it a graph. And yes you can tell the scoring has tightened over the years.
Here is a graph through 421 challenges
