This is the first Powerpoint presentation in a series that will teach you the statistical methods for the social sciences. After you view this first lesson, you will be able to answer the following questions: 1. How can statistical methods help you in your work? 2. What is the difference between a sample and a population? 3. What are descriptive statistics? and 4. What are inferential statistics?
