Which tool can visually represent data distribution?

A histogram is a graphical representation that organizes a group of data points into user-specified ranges, also known as bins. This tool provides a clear visual depiction of data distribution, showing the frequency of data points within each bin. By constructing a histogram, one can easily observe patterns such as the shape of the data distribution, the presence of outliers, and how data is clustered around certain values.

Unlike check sheets, which are used for data collection on specific attributes and frequencies without visual representation of distribution, histograms specifically highlight the distribution of the data across different intervals. Scatter diagrams are useful for identifying relationships between two variables, but they do not provide a clear view of distribution across a single variable. Cause and effect diagrams help identify the root causes of a problem but do not display data distributions. Therefore, the histogram stands out as the correct tool for visually representing data distribution effectively.
