The aim of this module is to provide students with a general background in statistical processes commonly used in the optometric and vision science literature, through application of statistics on sample data sets. A general background in statistics is developed so that statistical techniques used in the optometric and vision science literature may be evaluated. The background in statistics gained in this module will be used as the preparation for the project module.
