Sampling can happen when you apply segments, secondary dimensions, or filter your Google Analytics reports. Whenever we modify our standard reports or create custom reports, Google has to query our data, which can lead to sampling. Basically, Google estimates the data based on a percentage of sessions.
How does Google Analytics sampling work?
As mentioned before, Google Analytics samples your reports based on the number of sessions. Each version of Google Analytics has a different session limit. For Universal Analytics, sampling kicks in when your ad hoc reports have 500,000 sessions at the property level for any chosen date range.

Is sampling applied to reports before segmentation?
Save Your Time & Efforts – Buy Answersheet! Explanation: Analytics applies segments after it samples the property-level data, and after it applies filters, which can also reduce the number of sessions included in a sample.
What type of sampling methods are there?
There are two types of sampling methods: Probability sampling involves random selection, allowing you to make strong statistical inferences about the whole group. There are four main types of probability sample.
- Simple random sampling.
- Systematic sampling.
- Stratified sampling.
- Cluster sampling.
What is sampling in big data analytics?
Data sampling is a statistical analysis technique used to select, manipulate and analyze a representative subset of data points to identify patterns and trends in the larger data set being examined.
What does Google Analytics sample data for reporting?
Since Google Analytics pre-processes data for your standard reports, including the Audience, Acquisition, Behavior and Conversion reports, these reports will include unsampled data. So you will only see data sampling if you modify a standard report and the data range includes more than 500,000 sessions.

How can sampling problems be avoided?
Minimizing Sampling Error
- Increase the sample size. A larger sample size leads to a more precise result because the study gets closer to the actual population size.
- Divide the population into groups.
- Know your population.
- Randomize selection to eliminate bias.
- Train your team.
- Perform an external record check.
