Statistics is a mathematical method of determining trends and deviations from trends via probabilities. Essentially no results are absolutely certain, there is always a probability of alpha or beta errors. However, from the data, you can make a specific decision to accept or reject the null hypothesis.
This should give you a start. Thanks for asking.
