Discuss the difference between systematic error and random
error. Make sure to note how each of these effects (or does not
affect) our models. In doing so, note the influence these have on
statistical power and how this impacts the model.
What is the relationship between the familywise and per
comparison error rates? What happens to the familywise error rate
as the number of comparisons increases?
Examine the results of Part I. What is the relationship between
the three voltage readings: V1, V2, and
VTOT?
From the equivalent resistance readings for the series
circuits, can you come up with a rule for the equivalent resistance
(Req) of a series circuit with two resistors?
Examine the results of Part II. What do you notice about the
relationship between the three voltage readings V1,
V2, and VTOT in parallel circuits?
From the equivalent resistance readings for the parallel...
Suppose you discovered a systematic relationship between the
priceearnings ratios of stocks and the performance of stocks. In
other words, knowledge of a firm’s price-earnings ratio proved
helpful in predicting which stocks would show superior performance.
Would this evidence be consistent with any of three versions of the
efficient markets hypothesis?
a) Why are repeated measures designs more powerful than between
subjects designs? Mention the error term.
b) If you were to compute a repeated measures ANOVA as a between
subjects ANOVA how would the results differ?
