Table 2.

Difference between the indices on the two sole (left and right) for nondiabetic people before the walk in the regions 1, 2, 4, 6 and 7 (see Figure 1). Here we can see the most important statistic of then like mean, the standard deviation (sd), the standard error of the mean (sem), interquartile range (IQR), the coefficient of variation (cv), the degree of distortion from the symmetrical bell curve or the normal distribution or the measure of symmetry (Skewness), the measure of whether the data are heavy-tailed or light-tailed relative to a normal distribution (Kurtosis), and the quartiles.
