Chemistry is the branch of science that explains matter, specifically its properties and behavior. As it establishes a relationship between the basic and applied scientific disciplines, it is known as the central science. Some of the subdisciplines include analytical chemistry, organic, nuclear, and ...
Pattern recognitionQualitative pattern recognition methods find important applications in the chemometric sector to extract structured information from complex experimental data. Two main strategies can be distinguished: unsupervised analysis, aimed at investigating on the presence of groupings within the ...
First, we will discuss the definition of quantitative data. In any basic statistics class, most of the data we will be working with is quantitative.Quantitative datais data which is numerical in nature, that is, quantitative data consists of numbers which it makes sense to do math with. If...
