Table 1. Classification of statistical methods as reported in journals.

Category Brief description
t -tests One-sample, matched pair and two-sample t-tests
Contingency tables Chi-square tests, Fisher's exact test, McNemar's test
Pearson correlation Classical product moment-correlation
Simple linear regression Least squares regression with one predictor and one response variable
Power Loosely defined, includes use of the size of detectable (or useful) difference in determining sample size
Epidemiological statistics Relative risk, odds ratio, log odds, measures of association, sensitivity, specificity
Adjustment and standardization Pertains to incidence rates and prevalence rates
Multiway tables Mantel-Haenszel procedure, log-linear models
Non-parametric tests Sign test, Wilcoxon signed-rank test, Mann-Whitney test
Non-parametric correlation Spearman's rho, Kendall's tau, test for trend
Analysis of variance Analysis of variance, analysis of co-variance and F-tests
Multiple comparisons Procedures for handling multiple inferences on same data sets, includes Bonferroni techniques, Scheffe's contrasts, Duncan multiple range procedures, Newmann-Keuls procedure
Transformation Use of data transformation (e.g logarithms) often in regression
Multiple regression Includes polynomial regression and stepwise
Life table Actuarial life table, Kaplan-Meier estimate of survival
Regression for survival Includes Cox regression and logistic regression
Other survival analysis Breslow's Kruskal-Wallis, log-rank, Cox model for comparing survival
Cost benefit analysis The process of combining estimates of cost and health outcomes to compare policy alternatives
Sensitivity analysis Examines sensitivity of outcome to modest changes in parameters of model, or in other assumptions
Other Anything not fitting above headings, includes cluster analysis, discriminant analysis and some mathematical modeling
