tests the difference between observed and expected frequencies by chance
Chi-Square test
nonparametric analog of Pearson's r that is based on ranked data &/or non-normal distribution
Spearman Rank Correlation Coefficient
Proportion of existing cases relative to the total population at a given point of time
Prevalence
for of chi-square used with 2x2 tables involving correlated samples (subjects are their own controls)
McNemar test
Occurs when IVs in a regression are correlated with each other, providing redundant information
Collinearity
correlation statistic for parametric data
Pearson product-moment coefficient
Rearranging the orientation of axes and variables without altering the underlying relationships
Factor Rotation
occurs when independent variables in a regression are correlated with each other, providing redundant information.
Collinearity
a test’s ability to obtain a negative test when the condition is absent
Specificity (Sp)
a form of prediction where dependent and independent variables are categorical, predicting group membership
Logistic regression
a procedure used to explore the underlying structure of a set of variables related to a latent trait
Exploratory Factor Analysis (EFA)
a test’s ability to obtain a positive test when the target condition is really present
Sensitivity (Sn)
used to confirm a hypothesis about underlying constructs by proposing a model and verifying it through factor analysis
Confirmatory Factor Analysis (CFA)
minimal amount of measurable change not happening by chance
Minimal detectable change (MDC)
Tell us how much of the total variance is explained by a factor.
Eigen-value
test statistic for determining internal consistency
Cronbach’s alpha
used to assess test-retest or rater reliability
Intraclass correlation coefficient (ICC)
common test used when both X and Y are dichotomous
Phi coefficient
involves the development of an equation to calculate predicted values of Y from X
Regression
allows for prediction of Y using a set of several independent X variables
Multiple Regression
