Problem of multiplicity starts from which type of error?

Multiplicity is the inflation of _______ over multiple tests

Multiplicity control procedures are based on which t statistics?

Put the Multiple Comparison Tests in order from least to most conservative [blank_start]Fisher LSD test[blank_end] [blank_start]Hayter-Fisher test[blank_end] [blank_start]Tukey & Tukey-Kramer test[blank_end] [blank_start]Games-Howell test[blank_end] [blank_start]Dunnett's test[blank_end]

Which is the most conservative multiplicity control adjustment?

Dunn test with Bonferroni adjustment to alpha is [blank_start]less[blank_end] powerful with all-pairs comparison, and is reccommended to only be used for [blank_start]less than all-pairs[blank_end].

__________ is the most universal and most conservative multiplicity control adjustment. If a difference is found with this adjustment, a difference will be found with any adjustment.

Steps for Dunn test with Bonferroni adjustment: 1. calculate [blank_start]ANOVA-modified Two-sample t[blank_end] 2. calculate [blank_start]P value for each comparison[blank_end] 3. reject null hypothesis if P<[blank_start]Bonferonni alpha[blank_end]

Steps for Bonferonni adjustment to alpha 1. calculate [blank_start]a test statistic[blank_end] for each comparison 2. calculate [blank_start]P value[blank_end] for each comparison 3. calculate [blank_start]Bonferroni alph a[blank_end] for total number of comparisons 4. reject the nul if [blank_start]P < Bonferroni alpha[blank_end]

FISHERS LSD TEST --used for [blank_start]all-pairs comparison[blank_end], [blank_start]may control familywise error rate[blank_end] Procedure: 1. calculate [blank_start]ANOVA-modified Two-sample t[blank_end] 2. reject null hypothesis if [blank_start]t>t(table)[blank_end]
