Using regression analysis, he developed the following equation:
Using regression analysis, he developed the following equation:
−
:<math>\mbox{
[[
Porosity
]]
} = 18.60 + (4.73 \times \mbox{in quartz}) + (17.37/\mbox{sorting}) </math>
+
:<math>\mbox{Porosity} = 18.60 + (4.73 \times \mbox{in quartz}) + (17.37/\mbox{sorting}) </math>
−
