There are various formats of qualitative chemical analysis laboratory experiments for the general chemistry curriculum. Most of them take the form of following a scheme for the detection of cations or anions (1–4). A few of them make the problem interesting by introducing the laboratory in the...
Quantitative research is the opposite ofqualitative research, which involves collecting and analyzing non-numerical data (e.g., text, video, or audio). Quantitative research is widely used in the natural and social sciences: biology, chemistry, psychology, economics, sociology, marketing, etc. ...

Quantitative observation is often also used to compare the effectiveness of an intervention.Example: Quantitative observation in teachingYou are interested in the effectiveness of a new teaching method on student performance in a chemistry course. Specifically, you’d like to determine if a new ...
Overview of Chemistry Terms The scientific study of matter's characteristics and behaviour is known as chemistry. Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, ...
Real-time PCR results can either be qualitative (the presence or absence of a sequence) or quantitative (copy number). Quantitative real-time PCR is thus also known as qPCR analysis. In contrast, PCR is at best semiquantitative. Additionally, real-time qPCR data can be evaluated without gel...
