Statistics for stuff that has unequal length is tricky. Reminds me of the days there I did packet sampling on the LAN and as the length distribution is bimodal statistical math using means as assumption yielded misleading results.
I ran into this many years ago when trying to inspect spectral content of data from a fancy oscilloscope that had sub-sample accurate timestamps.
There are some tricks to solve my problem. The general term for it is "periodogram".
