I am doing an experiment where I get two values in two cases. Let's say the values are 10 in case 1 and 15 in case 2. For case 2, I want to report how high it is compared to case 1 in terms of percentage.
If I calculate (15-10) / 10 = 0.5, so can I say the result for case 2 is 50% higher compared to case 1 ?
If the score for case 2 was lower, e.g. 5, then if I calculate (10 - 5)/10 = 0.5, o can I say the result for case 2 is 50% lower compared to case 1 ?
