Monitoring Microbes in Purified Water: A Statistical Approach

What is it about?

Shewhart Control Chart in Microbiological Quality Control of Purified Water and its Use in Quantitative Risk Evaluation is a research article that investigates the use of the Shewhart control chart in assessing the microbiological quality of purified water. The Shewhart control chart is a statistical tool that can be used to monitor the variation in a process over time. By plotting data points on a chart, it is possible to identify trends, patterns, or unusual variations that may indicate a process is out of control.   The article applies the Shewhart control chart to monitor the microbiological quality of purified water. The authors collected data on the number of microorganisms found in samples of purified water and plotted the data on a Shewhart control chart. They then used the chart to identify any trends or patterns in the data and to assess the microbiological quality of the purified water. Overall, the article found that the Shewhart control chart is a useful tool for monitoring the microbiological quality of purified water. By identifying trends and patterns in the data, the chart can help to identify potential problems with the water purification process and take corrective action.
