Final answer:
To decrease logged data without statistics, one can employ clipping levels, log analysis, or alarm triggers; these methods set thresholds, scrutinize patterns, or notify only for critical events, respectively.
Step-by-step explanation:
To reduce the amount of logged or audited data using non-statistical methods, one can use clipping levels, log analysis, or alarm triggers. Clipping levels set a threshold value, beyond which data is not logged or alerted. Log analysis involves reviewing logs to identify patterns or events of interest to reduce the volume of future logs. Alarm triggers are configured to initiate notifications only for critical events, rather than recording all events.
