normal

1. agreeing with the regular and established type. When said of a solution, it denotes one containing one chemical equivalent of solute per liter of solution; e.g. a 0.5 normal (0.5 N) solution has a concentration of 0.5 Eq/l. The use of standard units (Eq/l) is now generally preferred in pharmacy and clinical medicine although elsewhere molarity (M) is used.

2. in the context of infectious diseases, not immunized or infected.

3. statistically speaking, the values of a variable which follow a bell-shaped or Gaussian distribution.
