exemplars

[Terry Moffat]

Hi,
 
I would have thought that to measure thickness they should be using a micrometer, and the reading initially should have been 2.00 mm.
 
To use anything else would be unusual in that situation.
 
I suspect we have a typo in the exemplar.

Hi all,

I posted a comment earlier today concerning sf and received several
replies to me personally rather than to the list. I guess if one just
clicks on reply with this list the reply only goes to the person doing the
posting rather than the whole list.

I'm sure that Marilyn and Fenella won't mind my copying their comments to
the list to inform others:

Since the sf is an indicator of the accuracy of the instrument I don't
think the sf can be increased by mere mathematical processing - it is
wholly dependent upon the smallest increment in the actual measuring
device.  That's my take on it.
Fenella, Manurewa High School

Totally agree with you (& not the exemplar)

Thank you. I will stick to my original practice.

Andy
