Runs Test Above and Below the Median
If nAbove>20 or nBelow>20, a test statistic, t, can be calculated
and
compared to a Student's t distribution (two-tailed,
df=infinity).
Otherwise, see specially tabulated critical values
in Table AA in
'Statistical Tables' (F.J. Rohlf and R.R. Sokal,
1995).
If P<=0.05, there were fewer or more runs than would be expected
by
chance. This implies that the events probably
did not occur randomly,
and that each event was probably not independent
of the previous
event.
Runs Test Up and Down
If nTotal>=25, a test statistic, t, can be calculated and compared
to Student's t distribution (two-tailed, df=infinity).
Otherwise,
see specially tabulated critical values in Table
BB in 'Statistical
Tables' (F.J. Rohlf and R.R. Sokal, 1995).
If P<=0.05, there were fewer or more runs than would be expected
by
chance. This implies that the events probably
did not occur randomly,
and that each event was probably not independent
of the previous
event.

Testing skewness=0 and kurtosis=0 tests if the numbers have a
normal distribution.
If the probability that skewness equals 0 ('P(g1=0)') is <=0.05,
the distribution is probably not normally distributed.
If the probability that kurtosis equals 0 ('P(g2=0)') is <=0.05,
the numbers are probably not normally distributed.
