Expert writing Tips
Best practice
When describing changes in quantities or values, ensure that the relationship you are describing is truly proportional. Avoid using the phrase if the changes are merely correlated but not mathematically proportional.
Common error
Avoid using "in the same proportion" when you actually mean a general correlation. Proportion implies a precise mathematical relationship, not just a trend.
