Worked Examples

Statistical tables

To complete some of the examples below you will need access to a table of "critical values" for the probability distribution that test uses. There are copies of these tables in your lab manual as well. The tables you will need are:

General overview

For each of the calculation topics we cover in class I have created introductory and example videos. These are the same videos on the "Weeks" page, but organized differently.

The first set of examples are available on the YouTube channel using the link provided.

The second set of examples are posted as a blank sheet with the data and questions and a corresponding completed version.

To make best use of these I recommend watching the introductory video and the examples videos while taking your own notes first. Studies have shown that actively taking notes helps learning much more that passively watching a video. You can use the PDF to check your notes. Then try performing the calculations on the first blank sheet (this is the data set from the online video) with minimal use of your notes. After that, try the examples on the second sheet and check your answers on the completed sheet.

Many of the assignments and questions on exams are very similar to these examples so spending time with these worked examples will help you considerably.
