Here's some blatant confirmation bias for you .....

"Laura does seem to learn how to play her opponents, a narrow loss at first meeting is often followed by a clear win at the next rematch."

... or is it?

(I am confident that Indiana will now produce an analysis showing that the above quote from Peter Too is statistically unimpeachable).

bleh



I can find one case when Laura lost to the same person twice,

three times when Laura beat someone the 1st time and then lost to them the 2nd time (all at the junior level)

seven times when Laura lost to someone the 1st time and then beat them the 2nd time.

Does this show a pattern?

Oh I think so biggrin well done!!!

However,   harking back to the comments about 'confirmational bias' - there is always a bit of that going on - no such thing as total objectivity - ' the experimenter  is  always part of the experiment'   and so on.  But please don't draw me further.

 

Having watched Laura play at least three matches live, courtside,  I do have my own views on  her play, and sometime I might try to share them.

I also think that watching matches live ( I went to the 02 last year and then a few tournaments here in the Midlands this year) is a completely different experience to watching on stream, and is what really 'hooked' me and turned me into a Tennis Addict.

Gee, it is going to get rather time consuming if folk can't make observations such as that they think a) partly or fully based on b) without being accused of blatant confirmation bias unless they have full statistical back-up for b) and even if the accuser has nothing showing otherwise.  Once upon a time folk were able to share fairly uncontroversial thoughts stated in that way without such a palaver.

I already spent quite a lot of time setting out Laura's win / loss vs ranking statistics for this year to refute your "periodic outperformance" and "return to norm" stuff about her wins and loss here.  

Not that you acknowledged this in any way, but simply moved on to your next bit of sport, sorry next accusation of "blatant confirmation bias".  

Re the latest matter of Laura regularly winning return matches against opponents ( and evidently particularly as a senior ), I guess one counterpoint is that Laura is of course generally getting better ( and I am not going to give her whole career record to prove that statement  hmm.gif )  so all other things being equal one would expect her to do better in the return.  But it is interesting and my memory ( uinchecked ! ) is that some of these return wins have been pretty conculsive as indicated before.

Some of 'us' need to get a grip / a life / or develop reasonable thought processes...well done Indy on a final reply.

Btw I hate Laura when she wins so easily...

Getting bored now, sorry, but to try to draw a line under this interesting debate:

Pitt the Younger: Sirs, as I said to Chancellor Metternich at the Congress of Strasbourg: "Pooh to you with knobs on!"

(Blackadder, Dish & Dishonesty)

doh

(I was of course most impressed by Indiana's statistical analyses, less so by his not knowing about Confirmation Bias - possibly it wasn't on the college syllabus in the 1960s?)

no

Time, Gentlemen.

Incidentally, I think the loveliest bit of this tournament was Kimiko Date Krumm celebrating her 40th birthday by beating Sharapova and Hantuchova. Now there's someone who's had a really glorious return!

I think Eleanor Preston should be offered honorary membership of BT.net for this 'classic':

eleanorpres: "@laurarobson5 I hope you didn't fold under the pressure."

Any one of us would have been proud of wordplay as bad as that biggrin
