Bonferroni - Samenvattingen, Aantekeningen en Examens

Biostatistics Final Exam Definitions UTA 100% Correct Bonferroni-Holm Multiple Comparisons -In the context of an ANOVA, rejecting the null hypothesis means there is a statistical difference between at least two means, but it won't tell you where it is. You use this to discover exactly which means are different. -Only used for Model I ANOVAs -A t-statistic for a two sample t-test assuming equal variance Steps to Applying the Bonferroni-Holm Multiple Comparison Test Step 1: Calculate...

1.Bonferroni Test: When planned? Df used? α used? Which/how many contrasts allowed? What test statistic is used to find the critical value? - a.A priori b.Df = 1 c.αβ= αc d.Any and all contrasts allowed e.F 1.Define a 2-way interaction - a.The effect of one IV(A) on the DV varies across levels of another IV (B) 1.Define Carryover effects - a.The effects of earlier trials on the DV scores obtained in later trials 1.Define Experiment-Wise Type 1 Error Rate (αEW) - a.=the probability ...

Alternate Hypothesis (Ha) correct answers The experimental hypothesis that a difference or a relationship exists Biased Estimate correct answers An approximation for a parameter that contains systematic error so that it over- or underestimates the parameter Bivariate correct answers concerning two variables Bonferroni correction correct answers an attempt to reduce Type 1 error by using α / #tests to determine the critical value Causality correct answers the assumption that a change...

Phi includes what type of information - ANSWER-Info about a person's physical health, mental health, provided care and payment for that care What are three different types of PHI and examples for each - ANSWER-Written PHI- ensure that phi is not left on copy machines or desk tops Electronic PHI- ensure that computer monitors are covered or shielded from the public eye Oral PHI- do not talk about PHI in hallways, elevators, parking lots, or public areas What is the appropriate sequence ...

Eindopdracht voor het onderzoekspracticum Experimenteel Onderzoek met als onderwerp "Het effect van speciaal muziekonderwijs op de executive functioning bij kinderen" . Dit verslag is beoordeeld met een 9,1. Ik heb gebruik gemaakt van post-hoc toetsen met een Bonferroni correctie. Je kunt er ook voor kiezen om contrasten te gebruiken. Dat heeft in principe ook de voorkeur, omdat je daarmee niet hoeft te corrigeren voor het feit dat je meerdere toetsen uitvoert. (Post hoc past de alpha aan waa...

structural model logic (vs the first method) - correct answer focuses directly on what contributes to the divisions of the deviations of scores from the grand mean earlier method ANOVA - correct answer comparing a variance based on differences among group means to a variance based on averaging variances of the group what creates within groups variations - correct answer chance fac...

Met behulp van deze samenvatting en de samenvatting van statistiek 2 heb ik een 9,5 behaald op het tentamen. Deze samenvatting bevat alle nieuwe informatie die wordt gebracht in statistiek 3. De samenvatting van statistiek 2 bevat betere informatie over de onderwerpen die in statistiek 3 alleen herhaald worden. Het vak werd destijds gegeven door Melvin Vooren
