In this lesson, we are going to be talking about normal distributions again, but this time breaking it down into the PDF or probability density function and CDF or the cumulative distribution function. We are going to be talking about frequency charts which we have been doing before and then contrast it to this new idea, cumulative frequency of charts. We are going to do a very elementary review of calculus, and then we will talk about PDF for standard normal distribution and PDF for normal distribution. Later on we will move on to CDF and see what we get if we take integral of PDF. Some examples are included too.
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.
