The figures
Quartiles by size band
A median is the middle company: half of this sector sits below it. The quartiles are the companies a quarter and three quarters of the way up. Sample sizes differ from row to row because each figure is counted only where a filing states it.

the largest band this dataset separates
No figure for this size band clears the 50-company floor, so the whole band is suppressed.
What is not here
There is no trading figure on this page, and there cannot be
A small company files abridged accounts, which carry a balance sheet and no trading account. So nothing on this page says what these companies take in or what they keep, and no amount of sample size would change that. Anyone quoting a sector trading figure from this source is quoting something the source does not hold.
There is no figure here for all UK companies either. A middle value taken across incomparable sectors is a number about nothing, and it is exactly the unsourced rule of thumb these pages exist to replace.
Of the 25 figures this sector could report, 20 clear the floor and 5 are suppressed for want of companies.
