Introduction to Statistical Quality Control by Douglas C. Montgomery
Statistics Notes:
In any process, variation is inevitable. There must be some sort of variation in the products that affects their desired specifications. These variations can be due to assignable and non-assignable cause. Whatever the cause is, variations in the process should be identified and studied. Statistics is the most common way to do this. Statistics is a discipline that helps to gather, organized, analyze, interpret and present data. Statistics is divided into two types; descriptive and inferential statistics. Descriptive statistics gives the quantitative summary of data features e.g. mean, median, standard deviation etc. Inferential statistics uses the analyzed data to draw conclusions for a population e.g. hypothesis testing, estimations etc.
