the dispersion about the mean, and the standard error (S.E.) indicates 

 the degree of reliability of this dispersion. 



According to Hubbs and Hubbs (1953), a large amount of overlap 

 of the dark bars (S.E.) indicates a low reliability of the observed 

 difference between two samples, and any appreciable separation of 

 these bars indicates a high reliability. These same authors recommend 

 plotting one standard deviation on either side of the mean to indicate 

 probable subspecific difference by a nonoverlap of the bars. This 

 method indicates an 84 percent separation of the specimens by the 

 character being analyzed.
