Signal vs. Noise

"Signal" refers to meaningful information that reveals the true pattern or message you're trying to understand, while "noise" consists of random, distracting, or irrelevant data that obscures the signal. For example, in data analysis, the signal might be a real trend affecting sales, whereas noise includes random fluctuations or errors that don't reflect the underlying pattern. Distinguishing between the two helps in making accurate decisions and insights, ensuring that focus remains on the genuine information rather than being misled by irrelevant or misleading data.
