Re: Weighted Mean

Hi MathsIsFun;

Looks good and is easy to understand. Good work.

But I would still buy the Canon.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Weighted Mean

hi MathsIsFun,

Another clear explanation with good examples; well done!

I'm just wondering if it is 'safe' to use actual company names.

Could you be open to legal nastiness, because, for example, Canon might argue you have promoted a rival's product unfairly.  I think UK exam boards get around this by making up names eg.  Sany and Conan.  Just a thought for your protection.  ???

Re: Weighted Mean

Good idea Bob. Sany and Conan sound fun! Also Sonu and Canan ... or Soni and Canyn?

Re: Weighted Mean

On second thoughts, you'd better make Conan the preferred make.  Else out of the legal frying pan and into the barbarian fire.  eek

Re: Weighted Mean

Hi,

How about Cannon and Sonny?!
