Quantitative methods are research techniques and methods dealing with numbers and anything that is measurable. This module reviews the most commonly used quantitative methods in the area of animal breeding and animal genetic resources (AnGR). The module primarily addresses topics of relevance to scientists in the area of AnGR in developing countries, including both faculty in universities/colleges and staff in research institutions.

The core text includes links [green] and references to other parts of the AnGR Training Resources (CD), such as exercises, module texts, compendia and case studies. There are also links [blue] and references to literature and websites.
