control, and improve processes by using statistical techniques. The primary objective of SPC is to ensure that a process operates consistently and produces products or services that meet predetermined quality standards.
SPC consists of tools and methods that can measure and examine the process data to characterize the process and gain control.Statistical process control uses seven quality control tools and seven supplement tools. Quality control tools 1. Control charts Classical and most accepted statistical process t...

with ANOVA (34%), regression analysis (15%), Spearman’s correlation analysis (10%), and Pearson’s correlation analysis (8%) used most often to analyze variables (see Table 1 in Online Appendix A for details.) Four studies take more than one statistical approach to investigate the relation...
This was supported by two statistical measures: Kendall's Tau correlation coefficient with continuity correction, 0.000 (one-tailed p = 0.500); and Egger's regression intercept, −1.567 (one-tailed p = 0.280). Sign in to download hi-res image Fig. 4. Funnel plot of standard error by ...

Data gathered during the initial monitoring period will then help to establish limits that represent the performance of the process at the commercial scale. In general, statistical control limits should be set at the centerline plus and minus three sigma, which approximates to three standard ...
Full size table The majority of activity data is sourced from the statistical yearbooks published by the National Bureau of Statistics, resulting in a relatively low uncertainty of data. However, changes in statistical definition and scope, misreporting or non-reporting, and difficulties in adapting ...
