I Love Stats: Learning to Love Statistics
ADD FREE starts 15 April 2015
This course will help you develop a functional, satisfying and useful life-long relationship with statistics. To achieve that goal, we will take a non-technical approach. You will learn how statistics work and why they are so helpful in evaluating the world of information around us. You’ll learn about the logic of statistical thinking and the concepts (rather than the mathematical details and probability theory) that guide statistical inferences and conclusions. You don't need to be a math whiz to take this course. If you can add, subtract, multiply, and divide (or just be able to use a calculator to do that!), you will be more than able to handle what will happen as this relationship develops.
