beauty is on a distinguished road

I am solving a time-dependent problem using fluent. Fluent help says "You can set the Sampling Interval such that Data Sampling for Time Statistics can be performed at the specified frequency". However, I am puzzled by the relation between sampling interval and sampling frequency. I wonder whether the following equation is right.
sampling frequency=1\div(time step size\timessampling interval)

In addtion, how can I set an appropriate Sampling Interval, according to sampling frequency in the experiment?

Thanks for your help!
