If a movie has eight 5-star ratings and two 4-star ratings, it is rated 4.8 stars. A movie with just seven 5-star ratings, is rated 5.0 stars and thus is higher rated. The only thing is that because the one with 4.8 has more ratings, its rating is more trustful, but it definitely is not the highest rated. When something on the internet has over 250 ratings, you can say that it is trustful anyways. I hope this clears it up.

A better example might be that a video with 2000 ratings of which 1000 are positive and 1000 are negative, is obviously not higher rated than if it are just 999 ratings, all 999 being positive ones. On the old YouTube it would be the difference between 2.5 stars and 5 stars.

Back to your video. It has 843 positive ratings and 32 negative ratings as for now. That is 875 ratings in total which is definitely more than any video of that routine. Now, please keep in mind that it has 32 negative ratings.

Up to Tommy Wonder his video. That one has 409 positive ratings and just 5 negative ones, which makes 414 in total. Now, if you take those 5 negative ones and equal it with the amount of ratings your video has by deviding it with its total of 414 and then multiplying it with your total of 875, you will see that only 8 or 9 of those ratings would have been negative if Tommy his video would have had as many ratings as yours. Since 8 or 9 is obviously less negative than 32, I hope you understand it now. It means that Tommy his video is rated 4.94 out of 5 and yours is rated 4.82 out of 5. Also, I am sure that there are people with videos of the routine which have absolutely no negative ratings and so those are actually rated the highest.

"Chicago's favorite Band!" and "New Improved soap!" are either people their opinions or it are facts. If the band in question won a competition and earned that title they could put that on their poster as a fact. If anyone just said it, the band can put it on their poster or anywhere else as an opinion as long as it is in quotation marks. If the soap really improved or if anyone said so, it is either a fact or an opinion as well. If it is about TV series, it will always be opinions, if it is about hand soap it can be a fact too. Actual statistics are not to mess with. In many countries that is even against the law.

Hope you had a good night.
I asked the brewmaster at work who is a brilliant mathematician.

It depends on how you look at it.
For the people that have watched and voted, I have 842 positive which means .615% of the viewers liked my video.
Tommy has 408 positives which comes out to .419% of the viewers that voted, liked it.

Now, out of all the people that voted for me, 874. 96% liked it.
Tommy comes out to 98.5% of all votes liked his.

Another way to look at it is:
The negative ratings cancel out the positive ones.
MY VIDEO
842 Positive
-32 negative
810 total positive ratings

TOMMY"S VIDEO
408 Positive
- 6 negative
402 total positive ratings

I have approx. twice as many positives as Tommy But I have 29% more views so if you take 29% of my positives away it gives me approx. 597 positives to Tommy's 408.
My video is still higher rated.

So will I change my poster? No.. But Tommy is getting close.
