Introduction to Statistics

From this page you can access a collection of videos and handouts dealing with important areas of Introductory Statistics. For Maynooth University students, this material is typically covered in parts of Introduction to Statistics (ST122, MT222S & MT221A), although some materials will be relevant for more advanced courses also. These resources are not a replacement for the material covered in your lectures and assignments, rather you should use them as extra support to aid your understanding of any material you may have difficulties with.
