In this lesson, we are going to be looking at shapes again but now we are going to be calculating skewness and kurtosis. We could not do this before when we covered shapes because we needed to know something about variability first. We are going to cover the concept of skewness and then we are going to try and connect that to calculating skew. Then we are going to be talking about how to interpret the number that you have calculated and also what that number will tell you about the relationships between the measures of central tendency. Then we are going to talking about calculating kurtosis and how to interpret it.
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.
