Statistical quality control involves using statistical methods to monitor and improve the quality of products and processes. This includes collecting and analyzing data, setting quality standards, identifying sources of variation, and implementing strategies to reduce defects or errors. Statistical tools like control charts, hypothesis testing, and regression analysis are commonly used in statistical quality control.
Control groups are more commonly used in quantitative research to compare outcomes with a standard or no treatment group. In qualitative research, control groups are not typically utilized since the focus is on exploring experiences, perspectives, and meanings rather than testing hypotheses with controlled variables. The emphasis is on in-depth understanding rather than statistical generalizability.

Fixed effects in statistical analysis refer to variables that are constant and do not change across observations. Random effects, on the other hand, are variables that vary randomly across observations. Fixed effects are used to control for individual characteristics, while random effects account for unobserved differences between groups.
