When I compare values of descriptive statistics of my data from Excel and Minitab with statistics from Geostatistical Analyst (Histogram) there is a huge difference.

results from Excel and Minitab:
Variable  Skewness  Kurtosis
C1           -0.00     -0.82
C2           -0.82     -0.22
C3           -0.49     -1.03
C4           -0.21      0.49
C5           -1.45      2.10
C6           -0.26     -0.29

results from Geostatistical Analyst - Histogram:
Variable  Skewness  Kurtosis
C1            0.00      2.16
C2           -0.78      2.69
C3           -0.49      1.96
C4           -0.20      3.38
C5           -1.40      4.83
C6           -0.23      2.66

Those results shown in Geostatistical Analyst - Histogram are for the same data with no transformation performed. Why is there any difference?
