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

- 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
