Serc: Understanding the Standard Deviation: What Makes It Larger or Smaller?
Students develop a better intuitive understanding of what is meant by variability in statistics. Emphasis is placed on the standard deviation as a measure of variability.
Khan Academy
Khan Academy: Expected Value With Calculated Probabilities
Find expected value based on calculated probabilities. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
