How to properly explain a delta between 0.10 to 0.05 in proportions Assuming I have proportions for clicks to impressions of 0.10 for p1 and 0.05 for p2. This is equivalent to 10% and 5% click through rate.
One way is to say that p1 is 5% higher but can we even say that p1 is 100% more than p2 ? If so what is the best possible way to word this to not confuse the reader if only the delta is displayed and not the ratios
Option 1) The first proportion is 5% higher ?
Option 2) There is a 100% delta between both proportions
Edit: Typo in my delta number example (changed it)

As stated by Dave, $p_1$ is $100\%$ more than $p_2$, not $50\%$ (now corrected in the question), and is equivalent to saying that it is twice as much.
As for the other way of saying it (option 1), I believe that the convention generally is to say that $p_1$ is 5 percentage-points higher than $p_2$.
