Eastwood's BA201 Assignments

STUDY GUIDE FOR EXAM I, BA201, FALL

The test will place much more weight on chapters 3 & 4 than chapters 1 & 2. I have prepared a list of suggested practice exercises from the text. A student who thoroughly  understands these exercises, together with those exercises in the assigned homework, should be well prepared for the exam. As a part of this understanding, the student should be able to explain (with graphs where appropriate) the underlying concepts. Examples of the concepts include:  level of measurement, population, sample, standard deviation, coefficient of skewness, independence, etc.
