What is the difference between a normal distribution and a ...

The standard normal distribution is just a normal distribution scaled/standardized by the z-formula. Entering every xi value of the normal distribution into the z-formula will give you the standard normal distribution which by definition of the z-formula than has a mean of zero and a standard deviation of one.

LECTURE NOTES ON THE MAJOR SOILS OF THE WORLD

The strong cohesion of (micro-)aggregates and rapid (re)flocculation of suspended particles complicate measurements of the particle size distribution of Ferralsol material. The clay content found after the removal of iron and addition of a dispersing chemical is known as the `total clay' content.

The results of size and dispersion of iron cores along with their experimental parameters are listed in Table 2. A geometric standard deviation lower than 1.1 indicates a monodisperse size distribution, whereas for values above 1.4 indicates a wide distribution of size. Between these two values the size distribution is considered quite ...

How to tell apart iron-deficiency anemia and thalassemia ...

The red cell distribution width (RDW) is high in iron deficiency anemia because there is a wide variation in red cell size. In mild thalassemia (alpha or beta), the red cells are strangely all the same size; there is virtually no variation. So the RDW is low.
