If you look for example of the stats for Chen Jin, you will see he hasnt WOed against other Chineee players.. But retired on many occatins against other nations players..
Chen Long has to my knowedge not retired or WOed.
If you look at LDs WO-record things looks Very different!!
So depending on how you interpret the non-WOs of CL, CJ and the many WOs of LD you may come to different conclusions/interpretations..
And of course, even if you break it down to WOs by LD.. He has only WOed/retired 4 times against Chineese players and just 2 times against non-chineese player. So sample size and possibilities of statistical errors are of course HUGE as well.. )If it is some sort of statistical poof we are looking for anyway).

You have a good point there twobeer when you commented (which is very true);
"The number of WOs between CHN-CHN players are obviously bound to be bigger as they meet in so many more matches".
But when you read this comment from limsy (Post #97);
Even before limsy started to work on these statistics, based on current observations, whenever there are CHN-vs-CHN matches, I would say that 1 in 4 matches would end up as a walkover or a retired match. This is rather shocking as I compare Badminton with Tennis. For a RUS-vs-RUS Tennis match, I could expect only 1 in 100 matches that it would end up as a walkover or a retired match.

Rates is an important measure for comparison of two groups if you want to see the difference. In this thread, Limsy want to show the Chinese players has higher possibility of WOs than other countries. So we need a rate of WO per country if the sample size is large enough for the comparison.
Just like some medical researchers claim that smoker causes lung cancer and Tobacco company disagree. So you need to compare the lung cancer rates between smokers and non-smokers. You need to find big population for both groups.

Only if rates for other countries is totally different then you can claim that China players are more likely to WO.
10-31-2011, 09:27 PM #124
4 WOs out of 22 matches is 18,18%
7 WOs out of 34 matches is 20,59%
Secondly.. I think anyone that been studying up on statiscis know that based on these small samples here could be big statistical errors. And further more as has pointed out earlier.. Even if it DOES indicate that WO against a national team-meber is more likely than WO against a player from another cuntry, there really is not anything based on the statistiscs that would point to that this is unique for CHN.
Just an example based on your own statistics, that should underline the problem with small statistical samples...
total against own country player play until finish 0 retired or walkover 1 % 100% (infinite% with you calculus)
Does this prove that Germany is the worst WO kings???

Sample size is too small for Germany.

Tennis is individual sports while badminton is team sports.
Rus players are playing for themselves: big bonus and sponsor money.

To dicide whether to give a walkover, the player has to consider the chance to win. If some player is injured but the opponent is weak, he may choose to play. But if his opponent is too strong, he will consider twice about it, because more severe injury may happen. Some people say Roger Federer has received too many walkovers. The reasons are complicated, but you have to admit his opponents would think more before the match.
Tian Qing/Zhao Yunlei received a walkover from a Korean pair. If their opponent is not a Chinese pair, would they still do that? I won't deny some matched are "fixed", but it's really not that common.
And don't forget there are many retirements from Chinese players to foreign players in this French Open.

So based on your argument of how all the calculation should work out, LD number doesn't look as good as it was LMAO!!
So there is nothing we could do with this group of people HERE.

You many times pointed that we are bias fans of LCW (which is not entirely true) making all sort of accusations. But actually it is very clear now that in the face of clear cut stat results that someone like you is clearly a bias fan of CHN team. Not to mention your very favourite brand is Li Ning.
So how about this, lets stop pointing your finger of us being biased and get down to the very fact and objective discussion? Shall we?

I do not think you understand statistics. Grab some basic statistic books or google

It's no point you argue sample too small lah, China meet own team mates more cos they have more strong players lah, etc,etc. Even if calculate last 5 to 6 years, China's trend is same. You can accept or not accept, the percentage is such.
