Please excuse my dear aunt sally ( parentheses, exponents, multiplication, division, addition, and subtraction )
500 + 30% equals 650. 30% of 500 equals 150.
First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease. ( copy and paste from skillsyouneed.com )
Yes but to understand the answer, we need to dig into the mechanics of correlation. Correlation is a mathematical relationship between the change in two variables. For causation to occur without correlation, we must therefore lack that mathematical relationship.
