Hypothesis Testing
Ho: OR=1 ____ has no association with ____
Ha: OR=/=1 ______ has an association with ___
What is odds ratio?
We use this rule to find the probability of A or B
What is the addition rule?
The most common individual
What is mode?
What is normal distribution, equal variance and linear?
When 2 events can't co-exist
This unpaired sample T test has equal variance
What is a homoscedastic test?
Addition Rule (For non-mutually exclusive events)
What is Pr[A or B]=Pr[A]+Pr[B]-Pr[A and B]?
These trends result in higher precision
What is a small sd, large sample size and small SE?
When ANOVA does not meet assumption
What is Kruskal-Wallis ANOVA?
This word is represented by standard error
What is precision?
Positive dbar
What does treatment 1 has a larger value?
P[A and B] =/= P[A] X P[B]
What is A and B are not independent?
We use this kind of graph to estimate the median
What is IQR?
These 2 nonparametric tests use binomial distribution
What is Wilcoxon-Signed Test and Regression?
When the variances are unequal
F Calc > F Crit
What is a heteroscedastic test?
Ho: There is no interaction between ___ and ___
Ha: There is an interaction between ___ and ___
What is ANCOVA?
When a specific outcome of one random trial eliminates that outcome from the possibilities, which changes the probability of values for subsequent trials
What is sampling without replacement?
This test sets up your range of values that you are confident your estimate lies within
What is 95% Confidence Interval?
This tests deals with rearrangements (or repetition) of data you collected
What is a permutation test?
CD>1
What are clumped events?
The independence rule can be applied for this test when trying to find the expected frequencies
What is Chi square test of independence?
Conditional Probability (formula)
What is P[A|B]= (p[A and B])/(P[B])
Positive sign test
What value lies above the null hypothesis for a Wilcoxon-Signed Rank Test?
This nonparametric test involves calculating the sums of squares along with finding the test statistic and critical value
What is Spearman's rank correlation?
When the effect of one variable depends upon the state of the other variable
What is interaction?
