To minimize the number of values rendered NULL due to aggregation thresholds, you can:
- Use more granular dimensions in your final GROUP BY statement
- Look at certain dimensions in combination rather than in isolation
- Reduce the time window of the query
- Broaden any filtering that may be in place on the query
Explanation:
The correct answer is indeed Broaden any filtering that may be in place on the query. To minimize the number of values rendered NULL due to aggregation thresholds, broadening the filtering in the query can help increase the likelihood of having sufficient data to meet those thresholds. By relaxing filters or expanding the criteria, you allow for a larger set of data to be included in the aggregation, which increases the chances of having enough data in each group to avoid NULL values. This approach helps ensure that smaller or more specific segments are not excluded, which might otherwise result in insufficient data to meet the minimum requirements for the aggregation, leading to NULL values.
