In this lesson our instructor talks about expected values and variance of probability. She talks about example situation and some special cases. She discusses linear transformations, n independent values of x, and random variables. Three complete example videos round up this lesson.
Expected Value & Variance of Probability Distributions
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
This book provides a clear and methodical approach to essential statistical procedures. It clearly explains the basic concepts and procedures of descriptive and inferential statistical analysis. This book features a new emphasis on expressions involving sums of squares and degrees of freedom as well as a stronger stress on the importance of variability.
