RE: Per Quarter?

I'm updating a sales analysis created by my predecessor. Its title is "2009 Sales Analysis per Quarter". I wonder if the expression "per quarter" is correct, or if it's another example of bad business English. If that's the case, how would you change the title to indicate that the analysis contains data for Q1, Q2, Q3 and Q4? Thanks.

"by Quarter".

Wouldn't quarter days have got their name because they mark the quarters, not the other way around?

I'd also say 'by Quarter' (I'm in the UK, if that makes any difference)

#3 -- Yes.

"By quarter" does sound right in this context. The data are sales per quarter; the whole chart is analyzing sales "by quarter". But I probably wouldn't bother changing it. "Per quarter" won't confuse anyone, and changing it might make somebody wonder if the name change signalled a substantive change.

'Quarter' is fine - but since Q1, etc, refer in statistical analyses to quartiles, I'd favour '2009 Sales Analysis by Quartile'.

I don't think '2009 Sales Analysis by Quartile' works. That analysis is obviously of what sales were during each quarter of a year. To me Q1ff. as referenced by the OP meant first quarter of the year, second quarter of the year, etc. "Quartile" is "One of the three numbers (values) that divide a range of data into four equal parts." That could be anything, for instance, an analysis of sales by 4 age groups of sales people.

Don't be ridiculous, trax.

I would have left it at 'per quarter'. I didn't realise it was bad business english at all.
