- The storage modulus is described by a line of the form E' = A log
e
(f) + B, where f represents frequency. SE is the standard error of the coefficients A and B. R
2 is a squared correlation coefficient and shows how well the line fits the data points. If p < 0.05 it indicates that the line is statistically significant. Loss modulus and phase angle results given as mean and standard deviation (SD).
