EBP2 Exam 2 Review

In multiple regression, the predictor variable with the greatest predictive power is the variable with _______.

For the previous question (case-control study), what primary outcome would indicate a harmful exposure?

Which of the following is the percentage of patients in the experimental group with a BAD outcome to a treatment?

_______ could involves organizing a large set of variables (10) into fewer abstract components (2 groups).

The _______ is a rough indicator of goodness of fit for regression line.

A weakness of the MANOVA is the difficulty interpreting the "combo" DV and need to perform post-hoc ANOVAs.

Beginning with all 5 IVs (R²=0.245), you sequentially remove 2 IVs, yielding R²=0.523. Which of the following is FALSE?

Instead of an independent t-Test to compare these groups, what is the best statistical test given the baseline data?

For multiple regression analysis, which describes a plausible adjusted R² given the unadjusted value, R² = 0.754?

For studying a very rare condition, which type of study is best suited and why?

Which of the following is FALSE regarding the ANCOVA?

You have data with a dichotomous DV and an ordinal IV. What is the best statistical test for prediction?

Factor A causes factor D (the DV). Factor B causes factor C, which in turn causes factor D. Select the best test.

For a cohort study, RR = 10.2, p = 0.01, and the CI @ 95% is (0.893, 5.234).

For interpreting logistic regression, which of the following is FALSE?

Which is the best test when data is nested within groups arranged in a multilevel ranking?

If EER = 0.20, and CER = 0.60, which of the following is FALSE?

From SPSS output for simple linear regression, R = 0.80. What is the correct interpretation?

For a case-control study, OR = 0.5, p = 0.001, and the CI @ 95% is (1.893, 5.234). What is the most likely exposure?

Given the table below, calculate the RRR for a bad outcome.
