A histogram is a powerful Six Sigma tool used to visualize the distribution of a dataset. It displays data in the form of bars, where each bar represents the frequency of data points within a specific range or bin. By showing the shape, spread, and central tendency of the data, histograms help identify patterns, trends, and potential outliers. They are essential for understanding process variations, detecting shifts, and making data-driven decisions. Histograms facilitate root cause analysis and process improvement by providing a clear picture of data distribution, enabling better quality control and operational efficiency.
