What is the purpose of the Bonferroni correction (and other
similar ‘corrections’)? How is it applied and what problem does it
fix? What is the cost of using these corrections?
Part 1. Contrast the Bonferroni correction with the false discovery rate procedure.
Part 2. Contrast correlation and causation. Can we conclude about correlation from observational studies or from randomized controlled studies? How about causation?
Part 3. When do we use survival analysis techniques?
Part 4. What are some features of time-to-event data?
Answer TRUE or FALSE for each of these
statements.
Multiple comparison testing using the Bonferroni correction is only
applied if we reject the null hypothesis in a one-way ANOVA.
TRUEFALSE [1 pt(s)] Tries 0/1In the rank-sum test, when the
magnitude of the test-statistic gets larger, the p-value gets
smaller. TRUEFALSE [1 pt(s)] Tries 0/1A p-value of 0.001 indicates
we should accept the alternative hypthesis. TRUEFALSE [1 pt(s)]
Tries 0/1A regression model that is statistically significant
according to an F-test establishes...
What is the purpose of activity-based costing? How is it similar
and how does it differ from job order costing and process costing?
Can an organization use both job order costing and activity-based
costing? Process costing and activity-based costing? Why or why
not? What types of companies are more likely to use activity-based
costing? Why?
What is the purpose of the EVA measure? In what ways is it
similar to Residual Income? In what ways is it different? How does
it differ from Return on Investment? Contrast these measures with
the Balanced Scorecard
How are the effects of a sexual assault similar to those of
other traumatic events? What psychological effects experienced by
many rape victims are the same as those manifested by veterans of
combat or by survivors of natural disasters, terrorist attacks, or
other traumas? Are these effects unique when the sexual offender is
someone close to the victim?
Name two different types of “correction factors” which must be
applied to data taken in an in vivo counter facility. What
techniques might be used to obtain values for each of these
factors?
