CAPM Practice: Demonstrate an understanding of common problem-solving tools and techniques

A histogram displays the distribution of data by grouping values into ranges (bins) and showing their frequency. When used to display defects by type, it helps teams see which defect categories occur most often, supporting prioritization of improvement efforts.

**Why not A:** Determining if two variables are related is the purpose of a scatter diagram, which plots paired data points to reveal correlations. A histogram displays frequency distributions of a single variable across categories, not relationships between two variables.

**Why not C:** Visualizing the sequence of process steps is the purpose of a flowchart or process map. A histogram does not show sequential steps or process flows; it displays how frequently data falls into defined categories.

**Why not D:** Seeing if a process is stable over time is the purpose of a control chart, which plots data points against control limits over sequential time periods. A histogram shows a snapshot of frequency distribution, not time-based stability.
