Week 5: February 13

 

 

Update from
Your
Professor

 

Welcome to your 5th week!  

Last week we learned:

  • how to compute the sum of squares, variance, and standard deviation.
  • about the normal distribution and the area under the normal curve.
  • about z scores and t scores and how to compute both.
  • how to use SAS to determine standard deviation.

This week we will learn how to:

  • construct a scatter diagram
  • tell the direction of correlation
  • tell the degree of correlation
  • establish that correlation does not establish causation
  • compute the correlation coefficient
  • compute the coefficient of determination
 
Lesson Preparation

Each week this section will provide you with any necessary material that will be essential for you completing assignments.

Download the notes, have them read, and be prepared to ask questions:

  • Measures of Association Notes (Word file)
  • Check you answers here to Effects of Progressive and Sex-Object Images of Women in Advertising and Negative Behaviors of Boys When Interacting with their Father
    Normal Distribution and Standard Scores Key
  • Many of you may want to learn how to do the initial steps of solving for the correlation coefficient in Excel.  Below is a tutorial that will not only help you in learning these initial steps for correlation, but will also prove useful in the next lesson of simple linear regression
    Excel Tutorial
  • You will need to complete the following guide in order to do this week's assignment in Blackboard.

Review last week's lesson by completing the Measures of Variability Review Quiz before moving on to the lesson this week.
