140.612.94 STATISTICAL REASONING IN PUBLIC HEALTH II

Department:
Term: 4th term
Credits: 3 credits
Contact: Felicity Turner
Description:

Provides a broad overview of biostatistical methods and concepts used in the public health sciences, emphasizing interpretation and concepts rather than calculations or mathematical details. Develops ability to read the scientific literature to critically evaluate study designs and methods of data analysis. Introduces basic concepts of statistical inference, including hypothesis testing, p-values, and confidence intervals. Topics include comparisons of means and proportions; the normal distribution; regression and correlation; confounding; concepts of study design, including randomization, sample size, and power considerations; logistic regression; and an overview of some methods in survival analysis. Draws examples of the use and abuse of statistical methods from the current biomedical literature.

New Learning Objective(s):
Upon successfully completing this course, students will be able to:
Recognize different study designs and Discuss the pros and cons of each
Learn methods for randomly assigning subjects to two groups
Describe the concepts of confounding and statistical interaction; discuss how to recognize each
Explain the relationship between power and sample size
Create a scatterplot to visually assess the nature of an association between two continuous variables
Interpret the calculated values of the correlation coefficient and the coefficient of determination, and Discuss the relationship between these two measures of association
Perform a simple linear regression using Stata and use the results to assess the magnitude and significance of the relationship between a continuous outcome variable and a continuous predictor variable and for predicting values of the outcome variable
Discuss why multiple regression techniques allow for the analysis of the relationship between an outcome and a predictor in the presence of confounding variables
Perform a multiple linear regression using Stata and use the results to assess the magnitude and significance of the relationship between a continuous outcome variable and multiple continuous and categorical predictor variables and for predicting value
Perform a multiple logistic regression using Stata and use the results to assess the magnitude and significance of the relationship between a dichotomous outcome variable and multiple continuous and categorical predictor variables
Perform a multiple logistic regression using Stata and use the results to assess the magnitude and significance of the relationship between a dichotomous outcome variable and multiple continuous and categorical predictor variables
Interpret the results from a proportional hazards regression model
