Statistics | The Science of Decisions
Details
NOTE: This course has been divided into two courses: Descriptive andInferential Statistics. If you are new to statistics, we recommend taking these courses instead.
We live in a time of unprecedented access to information...data. Whether researching the best school, job, or relationship, the Internet has thrown open the doors to vast pools of data. Statistics are simply objective and systematic methods for describing and interpreting information so that you may make the most informed decisions about life.
- The applications of statistics to everyday life
- Methods for acquiring data through observation and experimentation
- To organize and describe quantitative and categorical forms of data
- Anticipating patterns using basic probability and sampling
- Statistical inference through estimation and hypothesis testing
- Correlation and simple regression
- Ways of describing the strength of relationships between variables
It sounds strange to say, but math is not the focus of this class. To do well, however, it is necessary to have a basic understanding of proportions (fractions, decimals, and percentages), negative numbers, basic algebra (solving equations), and exponents and square roots.

Our mission is to bring accessible, affordable, engaging, and highly effective higher education to the world. We believe that higher education is a basic human right, and we seek to empower our students to advance their education and careers.
Education is no longer a one-time event but a lifelong experience. Education should be less passive listening (no long lectures) and more active doing. Education should empower students to succeed not just in school but in life.
