Summarization and visualization in order to explore ad hoc views of the data. Meta-analysis is the rubric used to describe quantitative methods for combining evidence across studies. Common Statistical Methods for Clinical Research with SAS Examples, Third Edition, is an applications book with minimal theory. Oxford: Blackwell Scientific Publications, 1994. American Statistical Association Section on Survey Research Methods (ASA-SRMS) Behavioral Risk Factor Surveillance System (BRFSS) Bureau of Labor Statistics (BLS) Cochran, W. G.

One sample t test • Measures: Mean of a single variable • When to use: Comparing a known mean against a hypothetical value • Assumptions: Variable should be normally distributed • Interpretation: If the p value is less than .05, the results are significant • What to use if assumptions are not met: Statistical Research Methods.
