A systematic sample of every 50th can throughout the day ensures that the sampling occurs at regular intervals over the entire production period, providing a comprehensive overview of the quality control process. This method is more representative of the entire production than selecting samples from specific time frames or using simple random samples that might miss systematic variations throughout the day.
