The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis. ...

PH is a measure of the concentration of H+ ions are free in solution. It is defined as pH = -log([H+]).
If you replace pH with y and [H+] with x, you get the function y = log(x). If you analyze how this function changes as you increase x, this will show you how pH varies as X changes. Remember, H+ makes a solution more acidic!
