This video explains statistical inference, which is the task of making statistical claims about the population.

In a typical research study, we are interested in saying something about a population, but for practical reasons, we do not measure everyone but use a sample.  The purpose of statistical inference is to justify generalizing from a sample to a population. If we measure a large effect (e.g., correlation, difference between two groups, etc.) in the sample and a large enough sample size, we can be reasonably confident that there is also an effect in the population. The main tool and the focus of the video is p value, which quantifies how much evidence we have to claim such generalizability.
