Document Summary

Probability: drawing is a random process, draw a sample from a population and ask a question. Based on your answer, you can make a guess about the population: probability distributions are infinite, you look at samples to make guesses about the population. Random sampling: we compare different variables, but we are not finding relationships, ex: Most human traits are distributed with a bell-curve. Sampling and sampling error: sampling error: non representativeness of population. It is the distance between the sample statistic and the population parameter. Central theorem sampling distance and population distance has the same mean. The larger the sample size, the better.
