This document discusses reducing noise in data presentations. It defines noise as irrelevant or misleading information, while signals are potentially meaningful data that can prompt good outcomes. Reducing presentation noise involves more than just visual design and includes the entire data life cycle from collection to user perception. Some strategies discussed are providing context, emphasis and clear design, considering how data is perceived and distorted, allowing for feedback and tuning of the data, and handling errors and data entry issues. The goal is to filter out noise and emphasize meaningful signals to help with decision making.
