Thanks Nick - sorry I am only getting used to the correct terms.
Yes it is correct, that I am looking at the -summarize- command in stata.
. sum latency_int
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
latency_int | 5760 1102.242 700.1589 2 1999
. describe latency_int
storage display value
variable name type format label variable label
-------------------------------------------------------------------------------
latency_int int %8.0g latency_int
.
. count
5760
.
. summarize latency_int, detail
latency_int

Percentiles Smallest

5% 57 2
10% 122.5 2 Obs 5760
25% 377.5 2 Sum of Wgt. 5760
50% 1221.5 Mean 1102.242
Largest Std. Dev. 700.1589
75% 1779 1998
90% 1902 1998 Variance 490222.5
95% 1948 1998 Skewness -.2200922
99% 1988 1999 Kurtosis 1.417508
And here also an extract from list
. list latency_int
