What is an example of an inferential statement?
If you want to make a statement about the population you need the inferential statistics. For example, it could be of interest if basketball players are larger than the average male population. To test this hypothesis a t-Test is calculated, the t-test compares the sample mean with the mean of the population.

How do you explain inferential statistics?
Inferential statistics requires the performance of statistical tests to see if a conclusion is correct compared with the probability that conclusion is due to chance. These tests calculate a P-value that is then compared with the probability that the results are due to chance.
