The relationship between the 50% span length of fiber (L₁) and the 2.5% span length of fiber (L₂) for a given cotton variety is given by
L₁ = L₂/2 + 5.
If the standard deviation (SD) of L₂ is 4 mm, that of L₁, in mm, would be
L₁ = L₂/2 + 5.
If the standard deviation (SD) of L₂ is 4 mm, that of L₁, in mm, would be
