Statistical Quality Control – IspatGuru
https://www.ispatguru.com/statistical-quality-control/
There are seven basic techniques employed for SQC. These basic techniques are (i) check sheets, (ii) histograms, (iii) Pareto analysis, (iv) control chart, (v) cause and effect diagram, (vi) stratification, and (vii) scatter diagram. Cause-and-effect diagram: a graphical tool to identify and analyze the possible causes of a problem or defect. Check sheet: a simple form to collect and organize data related to quality issues. Control chart: a statistical tool to monitor the variation and stability of a process over time. Histogram: a graphical tool to display the frequency distribution of a data set. Pareto chart: a type of histogram that shows the relative importance of different factors or causes of a problem. Scatter diagram: a graphical tool to examine the relationship between two variables. Stratification: a technique to separate data into different groups or layers based on some criteria.
