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

Counting the tallies: Installation Error = 12, Measurement Error = 4, Documentation Error = 10. Installation Errors occur most frequently. This raw data from the check sheet would often be transferred to a Pareto chart to visually prioritize improvement efforts.

**Why not A:** Documentation Errors have a tally of 10, which is fewer than the 12 Installation Errors. While Documentation Errors are the second most frequent defect type, they are not the most frequent.

**Why not C:** The three defect types have different frequencies: Installation Error (12), Documentation Error (10), and Measurement Error (4). They are clearly not equally frequent, as the tallies show distinct counts for each category.

**Why not D:** Measurement Errors have only 4 tallies, making them the least frequent defect type of the three categories. This is significantly fewer than both Installation Errors (12) and Documentation Errors (10).
