Document Summary
Use the numbers to answer some type of question. Numbers should use logic and be thoughtful ie. number of people at age to vote. You can get a sample size (ie. 200 men + 300 women) Result: 100 men + 150 women smoke. It seems like half of the sample size smoke. Generalizations only applies to members of that set. Now go back to the numbers and comparing the question, size and the results, Extending those results from a sample to a larger population. Essentially take the results to generalize to a larger population. Many studies are done using inferential statistics. If you have a good sampling method, large and representative, you can make those inferences. Ie. number of people who smoke in different countries (usa vs canada) The value of one country can be way more than the other. Ie. the population of canada is smaller than usa. Getting a part of the sample size of the entire population.
