Data Analysis To determine the average of the lengths and widths the following equation was used: Mean= (∠'â–'χ)/n The following equation was used to determine the standard deviation of the lengths and widths: Standard Deviation= √((∠'â–'(χ- χ Ì )^2 )/((n-1) )) The standard error of the mean was used to observe how far the lengths and widths were from the mean: Standard Error of the Mean= (Standard Deviation)/√n The density of the respective hair types was determined using the following: Density of the hairs= (Number of hairs...
