ReCap Part II (Chapters 5,6,7)• Data equations summarize pattern in data as a series
of parameters (means, slopes).• Frequency distributions, a key concept in statistics, are
used to quantify uncertainty.• Hypothesis testing uses the logic of the null hypothesis
to make a decision about an• unknown population parameter.• Estimation is concerned with the specific value of an
unknown population parameter.• We have now concluded the first third of course.• We move on to the second third, the General Linear
Model

Advantages of GLM approach
• One recipe vs. dozens• Less restrictive– e.g. name the test:
• 1 ratio ~ 1 nominal ___________
• 1 ratio ~ 1 ratio ___________
• 1 ratio ~ 1 ratio + 1 nominal ___________
• 1 ratio ~ 1 ratio + 2 nominal ___________
