Earn Statistics College Credits On Your Schedule. This course will introduce you to the study of Statistics. Statistics is a course involving numbers, but what’s relevant about the subject is the information an observer can obtain or learn from the numbers. Statistics is a science that involves not just numbers but also the gathering of information and an analytical process that helps achieve a goal. For example, a financial analyst may want to know the likelihood that the economy will fall into a recession next year. Used appropriately, an economist may apply the rules of probability and a level of confidence to answer the question.

Statistics is a skill set relevant to many fields: business, physical and social sciences, and even the arts. In this course, students will learn meaningful ways to describe data beginning with the qualitative and quantitative distinction. They’ll study basic statistical concepts and techniques for collecting data, interpreting relationships, and predicting outcomes. For example, a simple random sample is one way to collect information about a population. What’s the difference between a population and a sample and what can we learn from the data provided? You’ll just have to see! Students will also learn how to translate information into organized systems applicable to countless real-world scenarios.
