Statistics
According to Suresh (2014) there are many uses for statistics in health science including but not limited to: normal and not normal determinations in context of health and illness, accuracy of diagnostics, planning of experiments and analysis of results, observations on history related to a disease, assessment of treatment protocol and care/treatment interventions and compilation of population health statistics (p.383). Below are resources that can help you learn about the use and method of data collection for statistics within nursing.
