I would like to emphasize the percentage change in the treatment cost by the percentage changes in the share of non-hazard waste.

Can I say "Every 10 percentile increment in the share of non-hazard waste in total waste leads to a 10-percentile decrement in the unit treatment cost"

If not accurate, how to describe the trend in the figure?

  • You mean "every 10 percent", not percentile. A percentile is a grouping into one of 100 groups.

  • Every 10% increment in the share of non-hazard waste in total waste leads to a 10% decrement in the unit treatment cost? I was afraid people might be confused by the base of each 10% increment because an increase from 10% by 10% is 11%, not 20%...

  • That's true, "a 10% increment" could be ambiguous. But my point was that percentile is definitely wrong.

  • Ok, no percentile. Do you have any idea how to make the sentence more clear?

The math relationship you are describing is an 'inverse-ratio', which describes an output (waste) that gets smaller as the input (cost) gets larger. In your example, this is a 'proportional inverse-ratio', where every new unit of cost results in the same amount of new reduction in waste.
