True or False Evaluation

The statement implies that a p-chart is utilized for monitoring the fraction of defectives in a process's output.

Explanation

1. Definition of p-chart: A p-chart, or proportion chart, is a type of control chart used in statistical quality control. It focuses specifically on the proportion of defective items in a sample taken from a production process.

2. Purpose of p-chart: The primary purpose of the p-chart is to determine if a process is in a state of statistical control regarding the proportion of defects. It assists in identifying trends, shifts, or any out-of-control conditions that may indicate problems in the production process.

3. Use Cases: P-charts are useful in industries where the quality of the output can be quantified as defective or non-defective, allowing for continuous monitoring and immediate corrective actions when deviation from quality standards occurs.

Conclusion

Based on the definition and purpose of a p-chart, the statement is True. A p-chart is indeed used to monitor the fraction of defectives in the output of a process.
