Opinion Average Info

storyteller · Post by **storyteller** » Mon Nov 22, 2004 1:54 pm

Hi,

I wanted to suggest a small change to the Opinion Submission screen.

Right now there is a simple line of text that says, "5 = average"

Yet on everyone's profile page it displays the little chart on the right had side entitled "global average" that shows in a practical way that the ACTUAL average is much closer to eight than it is to five. Could we perhaps change that line of text on the Opinion submission page to say “8 = average”?

It just seems ignorant to have the screen display that message, “5 is average” when five is in fact NOT the actual average.

Thank you all for considering of this suggestion,
Storyteller of the Red Moon

The message is there to indicate that people should give 5s for videos that are average in the appropriate category. The global average is the overall average of what people actually give. Moving the goalposts would only confuse the issue.

We have a population size of existing opinions, N = 87,422
That is a lot of existing opinions.

Can 87,422 opinions be wrong?

How is it confusing to say, "Do what you are already doing."
Or "What you are actually doing is ok."

Why not bring the ideal and the actual into closer alignment?

Yes, they can.

Theory and application are different, there's no need to force them to be the same.

You assume that people leave opinions on crappy videos as much as they do on good videos. If you look at which videos have the most opinions left on them, you see that they are some of the highest ranking videos on the site. Crappy videos often wont have any opinions, or maybe 1 or 2. Thus the average given leans towards higher values. That doesn't mean that average videos still dont deserve to recieve 5's.

Took the words right out of my mouth.

There is a self-selection bias in all forms of survey measurement. It is no surprise that we can see a significant self-selection bias in this voluntary process of writing opinions. Most people who take it upon themselves to write an opinion do so out of a desire to offer accolades to what they have enjoyed viewing.

In theory we can predict that great videos will get a lot of opinions. In theory we can predict that crappy videos in fact receive no reviews or very few opinions.

In practice great videos do in fact get a lot of opinions. In practice crappy videos get zero or very few reviews. Which lead me to the question, in practice how many opinions does an average video get?

I would predict, at this point, than nothing will take place as a result of this thread, as public sentiment and thought demonstrates an acceptance and approval of the current setup.

Thank you all for your feedback.

assuming we have 87441 opinions on 45333 video entries. each video gets 1.93 opinions. however, a number of videos have been deleted (and the video count doesn't reflect this). and a number of video entries are fake or duplicates.

opinions are better as feedback for the creator than as indicators of quality for watchers. star averages are better as indicators of quality for viewers (given the video has received a good number of stars, say over 100).

bwah, the video count does go down when videos get deleted. it doesn't reflect the total amount of videos including deleted videos.

average given
* Count 41
* Originality 4.95
* Visual Quality 4.59
* Audio 4.66
* Action Sync 5.56
* Lip Sync 4.93
* Special Effects 5.21
* Effort 5.83
* Re-view-ability 4.83
* Overall 5.71

owned. I've reviewed mostly good, although I did a little stint of giving ops to newbs, which I didnt rate too low.

But you're right, I see a video with 10 10 10 10 and it has a major flaw, especially like video or audio quality wise, and I go OOOOOK. Also if you've watched a lot of vids, originality scores are lower since you've seen a lot of concepts before. I saw average = 5, and damnit, it is.
