QMB3200 Exam 2 Questions and
correct Answers
ANOVA - ANSWER-analysis of variance
- used to compare 3 or more means
response variable - ANSWER-Y, dependent variable (DV) - QN
Factors (QL) - ANSWER-Independent Variable (IV)
Factor Level - ANSWER-Selected value of IV
Treatments - ANSWER-combinations of factor levels (represent the population)
Assumptions for ANOVA - ANSWER-- normally disturbed
- Variation of each is the same
Fischer HOC test - ANSWER-- more liberal
- likely to make type I error
Bonferroni HOC test - ANSWER-- more conservative
- likely to make a type II error
Binomial - ANSWER-- 1 QL variable at 2 levels
- 2 possible outcomes
- Success and Failure
- S is denoted as p; F is denoted as q
- p = P(S) = 1 - P(F) = 1 - q
- Test Statistic = Z
- proportions must add up to 1
- must be at least 15
Multinomial - ANSWER-- "Goodness of fit"
- Test statistic: X2
- all expected counts at least 5
