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)

$p_1$ is not $50\%$ higher than $p_2$; $p_1$ is $100\%$ higher than $p_2$.
I would phrase it accordingly: $p_1$ is double $p_2$. After all, I would expect the event under consideration to happen twice as often under the conditions giving $p_1$ as under the conditions giving $p_2$.
In other words, if you make a dollar every time the event happens, you make twice as much money with $p_1$ as with $p_2$.
