I've Got the Power
This occurs when the null hypothesis is rejected but should have been retained
What is Type 1 Error?
The conditions of nonparametric testing
What are not having a normal distribution and variances not being similarly skewed?
Used to determine the differences among means when more than one IV is used
What is factorial ANOVA?
The difference between a nondirectional and directional hypothesis on the curve - difference of critical region
What is non-split into .025 and .025 vs. .05
The most effective way to increase statistical power
The consequence of a Type 1 error is....
What is leading to ineffective treatments being implemented?
The nonparametric testing parallel to Paired T-test
What is Wilcoxon matched pairs?
This combines ANOVA with regression analysis and is used if ANOVA appears to be biased
What is ANCOVA?
This is what helps to determine the probability that the null hypothesis is true
What is a significance test?
One of these does NOT increase statistical power: decreasing effect size, minimizing error, using a one-tailed test
This is when the null hypothesis is retained but should have been rejected
What is Type II Error?
The purpose of the chi-square test is
What is to analyze the frequencies of observations of categorial data?
This is used for studies using with subject-designs in which different levels of IV are sequentially adminstered
What is repeated measures ANOVA?
The three steps in hypothesis testing
What is 1. translating the research? 2. conduct study and analyze the data using an inferential statistical test and 3 determining whether to reject or retail null
Increasing effect size helps to increase statistical power because..
What is having a greater magnitude of differences between groups, so that fewer participants are needed?
Power is...
What is 1- beta? What is likelihood of rejecting the null hypothesis given that the null hypothesis should be rejected?
The nonparametric test parallel to ANOVA
What is is Kruskal-Wallis?
This is appropriate for studies using a mixed design - 1+ IV is between groups; 1+ IV is within subjects
What is Mixed (split plot) ANOVA?
The region of values that corresponds to the rejection of the null hypothesis at some chosen probability level
What is critical region or region of unlikely values?
This is the certainty a researcher has about the decision to reject or retail the null hypothesis
What is confidence?
The consequences of a Type II error...
What is can lead to effective treatments not being implemented?
The nonparametric test parallel to Student's T test
What is Mann-Whitney U?
This is used when blocking has been employed to control for an extraneous variable
What is randomized block factorial ANOVA?
The relationship between alpha and beta
What is an inverse relationship?
Name the 6 ways to increase statistical power
What are increasing alpha, increasing sample size, increasing effect size, minimizing error, using a parametric test, using a one-tailed test
