View sampled Google Analytics data in Looker Studio
Looker Studio uses the same sampling behavior as Google Analytics. If a chart in Looker Studio creates an ad hoc request for data in Google Analytics, standard sampling rules will come into play. The actual sampling rate is determined by Google Analytics at the time of the data request. You can't change this rate in Looker Studio.
Including today’s date may have sampling implications. If data appears to be sampled in Looker Studio but not in Analytics, make sure that you’re comparing the exact same date range and consider removing today from the date range.
Sampling and Analytics 360
Google Analytics 360 provides higher sampling rates than standard Analytics. Looker Studio supports these higher sampling rates for Analytics 360 users.
