The Lie Factor

The Lie Factor is a concept from data visualization that measures how accurately a chart or graph represents the data. It compares the size or length of visual elements (like bars or lines) to the actual numerical change they represent. If the visual exaggerates or minimizes the data’s differences, the Lie Factor is high, meaning the visualization is misleading. A value close to 1 indicates accurate representation. The goal is to keep the Lie Factor low, ensuring the visuals genuinely reflect the data’s true differences, helping viewers interpret information correctly.
