Dealing with numbers

























Many academic subjects expect students to present statistical data in their written work. It is usually better to support argument with precise numbers rather than vague statements:
 
Many French companies were forced to reduce their workforce.
 
35% of French companies employing less than 100 people were forced to reduce their workforce.
 
Numbers 1 - 10 are normally written as words; above that figures are used:
 
There are three types of ants on the island, which covers just 17 hectares. 
 
Note that there is no final 's' with hundred/ thousand/ million:
 
About seven million people died during the famine.

Too many statistics can be difficult for the reader to understand. The following phrases are commonly used to simplify numerical information:

one in ten, ten percent

a third/ quarter, fifth

a tenfold increase (10 x)

to double/ to halve

a small/ large percentage/ proportion

the majority ( + 50% )

a minority ( - 50% )

twice (2 x) as many
