Advanced Statistical Methods for Healthcare Research - ILT

Currently no upcoming Class Dates

Description

The first part of the course focuses on the Analysis of Variance (ANOVA) techniques which

allow you to test whether the means of several populations are the same. You will develop

an understanding of when to apply the techniques, how to apply them and how to interpret

the results.The second part of the course will build upon your knowledge of linear regression and will

introduce you to logistic regression. We will include categorical predictors in regression

models via dummy variables, discuss variable selection methods, model building

philosophies and learn how to run and interpret logistic regression in IBM SPSS Statistics.

Objectives

Please refer to course overview.

Audience

This intermediate course is for healthcare professionals who want to identify significant differences between two or more groups and who want to analyze binary outcome data using logistic regression methods.

Prerequisites

A good working knowledge of IBM SPSS Statistics Base and inferential statistics is required prior to attending this course. Attendance on the Statistical Methods for Healthcare Research course is strongly recommended.
