+# inconsistent readings for everything but wind shear, or more likely, smaller units and \
+# higher rates of change.
+# the difference between shr1's iqr and stddev is larger than that of shr2's (shr2's is \
+# quite close to its stddev), possibility of one minor outlier
+# none of the data is very skewed, the largest (absolute value) being 0.54896, and \
+# all of the data has negative kurtosis, meaning when distibuted, it will have a shallower \
+# peak than the bell curve (e^x^2)
+# the february and may datasets are similar in that their wind shears are similar, though \
+# mays is still larger. they are different in that mays SRH and CAPE are both much higher, \
+# so mays tornadoes are much stronger.
