Hey Guys;

This is going to sound awkward and kinda embaressing to ask, but, what is the exact definition of "Normal" in scientific (more specifically, Biomedical Science terms)?

I am fairly sure it is when more than 50% of the population are within that specific range but, I need some confirmation here.

Am doing a medical report and need to know the exact definition of "normal" should I be asked in the oral exam in 5 weeks to go with the medical report I am due to present.

Abnormal is usually defined as outside of 2 standard deviations of the mean.

About 95% of the population will fall within 2 standard deviations from the mean, and thus be normal. 5% will be abnormal with regards to statistical infrequency.
