ANOVA with R

06 Nov 2023 at 09:00 - 13:00


ANOVA with R

ANOVA example

Picture source: Fig.2 from Harp et al, eClinical Medicine Volume 39, September 2021, 101045
DOI: https://doi.org/10.1016/j.eclinm.2021.101045.

The aim of this short course is to explain why we have to analyse variances
if we want to compare group means using ANOVA techniques. This lecture is best taken with
the Linear regression with R course.
Please note that we cannot go into the specific data analysis problems of your particular project.

Instructor: András Aszódi.

Topics

  • The intuition behind ANOVA: Comparing the means of several samples by analyzing variances.
  • Technical details: One-way ANOVA techniques: prerequisites, omnibus F-test, post hoc tests.
  • Getting the sample size right: Power and sample size calculations.
  • The relationship between ANOVA and linear regression (optional).
  • Combination of effects: two-way ANOVA.
  • “Are these regression lines different?” Analysis of Covariance (ANCOVA) (optional).

Prerequisites

  • Mandatory: Good understanding of basic statistics concepts.
    If you have attended our Think Statistics with R course,
    then you are all set.
  • Recommended: Basic familiarity with R. Our R as a programming language course
    provides you with the necessary knowledge.
  • “Bring Your Own Data”

    You can bring your own data to this course and run
    a one-way ANOVA on it.

    Please prepare a comma-separated-values (CSV) file with UNIX line endings (n) that
    contains several (more than 2) columns corresponding to the groups of data whose means you would
    like to compare. All groups should contain the same number of observations
    (a “balanced” ANOVA design).

    Practical information

    Number of participants: minimum 5, maximum 10.

    Length: The course takes one half-day,
    from 09:00 to 13:00 with two short breaks.
