In this lesson, we are going to talk about F distributions. First we are going to review other distributions we have covered besides F, namely z and t. Then we are going to introduce the F-statistic, also called the variance ratio. We are going to talk about the distribution of all the ratios and finally what Alpha and P value mean in an F distribution. Eventually were are going to do a hypothesis testing with the F statistic. Youll also see that the idea is the same as T statistics and the others - we are just applying it to a different looking distribution.
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.
