Re: Preliminary & Quarter Final Results

The larger the player pool, the easier to field a team of players with grades close to the upper limit. If you want to open the possibility of smaller counties being able to compete in restricted competitions, you need the grading rule to be "average under" or "total grade" for the team. I believe ...

Re: A level maths question

Putting aside the outdated chess references and formula, question (i) shows how in my opinion, education isn't keeping up with how things are done in reality. Who would calculate that figure of r manually, having first worked out all those sums? Surely everyone would just put the data into Excel, p...

Re: A level maths question

The issue I have with that is that due to the way the question is structured, if you can't remember the formula in part 1, how many marks for this question can you get? I expect it's in the formula book. Indeed it is in the formula book. Even if you do get the value of r completely wrong you could ...

Re: A level maths question

r=0.400, which is significant at the 5% level (as >0.3783) So the (made up) data is evidence that maths ability and chess playing ability are related. I think this is a good A level stats question with only 2 of the 8 marks for working out r. Most of the marks were for applying the regression test ...

Vaguely relevant to how things are taught, but why teach the counting of the pieces off the board? Why not those on the board?
I normally encourage them to add up either on the board or off the board, depending on which is fewer.

Re: A level maths question

Then you use your brain to work out if the answer is reasonable or nonsense. Yes, but they don't! so it'd be impressive to be out by a factor of 10 and not notice. :P I have seen A level maths students solving equations with the aid of their programmable calculator and getting as far as something l...

Re: A level maths question

Surely everyone would just put the data into Excel, plot a graph, and choose the option in the settings to tell you what r is? And then when the answer is wrong by a factor of 10 they have no idea, because it's just a number. When I operated in the financial derivatives markets it was always fun to...

Re: Preliminary & Quarter Final Results

Blame the Surrey captain, the Cornwall captain and the Controller if you only got a four hour session ! Thanks. It would probably be a bit unfair to blame the Controller. The Controller is only involved in this to stop the Open teams agreeing to a time limit that would make the match not eligible f...

Re: Half-point bye ... Why ?

What's the raison d'etre of half-point byes in tournaments? Why to include them in a tournament? Speaking for myself - In English weekend tournaments, because we either have: - 1 round on Friday night, 2 rounds on Saturday and 2 rounds on Sunday; or - 3 rounds on Saturday and 2 rounds on Sunday. Th...

Re: Which Candidate Should the ECF Support in the FIDE Presidential Election?

The trouble with being a former competitor on "Countdown" is that I notice that "Glen Stark" is an anagram of "Strangle K", which should either worry Kirsan or me... I was looking for anagrams of Glen Stark a few days ago, but rather than think about it for myself, I took the 21st century approach ...

Re: Which Candidate Should the ECF Support in the FIDE Presidential Election?

But elsewhere in that ghastly Stalin-era bureaucracy called FIDE, it's a different matter. All those VPs, assistant VPs to the President; endless clutter of titles and self-importance signifying little, doing less. And the Commissions - 26 of them! Good grief, there's even a Commission on Commissio...

Re: Which Candidate Should the ECF Support in the FIDE Presidential Election?

The way the Rules Commission seems to work, and presumably the Rules Commission did in the past when Stewart Reuben was Secretary, is: 1. Everyone is invited to write to the Secretary of the Rules Commission with suggestions. Some Commission members will no doubt have their own ideas too. 2. The Cou...

Oh! I've just discovered you can change your vote on these polls!

If anyone saw a wobble in the figues a moment ago it's because I changed my vote and then changed it back again (So you'll be able to work out how I've voted :-( )
Well, at least you haven't drawn everyone's attention to it.
