A scatter diagram is used to assess the relationship between two variables. In this case, it can be used to analyze the relationship between storage temperature and the overall length of the metalcomponent. A scatter diagram helps in visualizing any correlation between the two variables. Reference: "The Quality Toolbox" by Nancy R. Tague, which provides descriptions and uses for various quality tools including scatter diagrams.

When subgroups are selected in a way that minimizes the opportunity for variation within a subgroup and maximizes the opportunity to detect variation between subgroups, this subgrouping is known as rational subgrouping. Rational subgrouping is a concept used in control charting to ensure that the data within each subgroup is homogeneous, making it easier to detect special causes of variation between subgroups.References:

According to ANSI ASQ Z1.4, switching from tightened inspection to normal inspection can occur when five consecutive lots have been accepted. This standard specifies the requirements for inspection by attributes, including the criteria for switching inspection levels based on the quality of consecutive lots.References:
