Students in this course learn about biostatistical methods and concepts used in public health practice and research. Emphasis is placed on interpretation and application of concepts rather than statistical formulas. Major topics include identification of levels of measurement, interpretation of narrative and graphical descriptive statistics, conceptualization of statistical inference and probability, and interpretation of commonly used statistical tests such as t tests, analysis of variance, correlation and regression, comparing proportions, contingency tables, and chi-square tests. Students are required to use the statistical computer package SPSS.
