NURS 414 Nursing Research: Reading and Evaluating Research

Formerly NURS 404 / 409 Nursing Research / Clinical Research Project

Evaluating Sources of Information

Critically Evaluating Research Articles

In Evidence Based Practice, you critically analyse research to evaluate the design of a study and its findings. These tools are used to help you to systematically work through different kinds of research papers step-by-step, assessing their quality and results. 

Structure of a Research Article - Quantitative

Quantitative research articles are usually written in a standardized format called the IMRaD format: Introduction, Methods, Results, (and) Discussion sections of the articles. There is also usually a Conclusions section. By following this conventional structure, authors ensure that readers of their articles will be able to readily locate the paper's critical elements.
