does not have everyone’s address, know that we call that “noncoverage” bias).
Lane (Online Stat Book): Make sure you’ve read the assigned pages (see syllabus). Pay
particular attention to points from the book that are brought up in class.
OnCourse readings: Make sure you know what each sampling technique entails and be able
to categorize each technique as probability or nonprobability and justify that

Conceptual
Be able to link the material from the last exam with the new materials. I will not ask you able
materials from the first exam
specifically
, but there are some questions that require
you to use concepts from the first exam in order to answer questions about the new
concepts. For example, I may ask you to calculate different expected values given
different conceptualizations and explain why this shows that a clear conceptualization
is important. In this example, you won’t have to define and come up with a
conceptualization, but you will have to know what it is in order to answer this
question.
Math
Probability: Be able to calculate the probability of an event given a count of the event. Also,

and be able to work backwards given this information.

Arithmetic Mean: Make sure you can calculate this. Be able to use the formula to work
backwards (e.g., if I tell you what the arithmetic mean is and how many cases there
are, be able to calculate the sum of the values).
