For example with changing the font size of a button:
Your null hypothesis is there is no difference in the number of clicks. Your alternative hypothesis is that there is an increase in number of clicks.
Your IV is the button font size. Your DV is the number of button clicks over a set period of time.
You randomly sample 50% of the population to State A (same button size) You put the other group into State B (increased button size)
You observe the number of clicks of the button.
You analyze this data, and can determine the statistical significance between your null and alternative hypothesis.
