Quantitative structure-activity relationship (QSAR)
(sometimes QSPR: quantitative structure-property relationship)
QSAR is the process by which chemical structure is quantitatively correlated with a well defined process, such as biological activity or chemical reactivity.
For example, biological activity can be expressed quantitatively as in the concentration of a substance required to give a certain biological response. Additionally, when physicochemical properties or structures are expressed by numbers, one can form a mathematical relationship, or quantitative structure-activity relationship, between the two. The mathematical expression can then be used to predict the biological response of other chemical structures.

DTR, or "Define the Relationship," typically affects individuals in romantic relationships who are navigating the boundaries and expectations of their connection. It often involves discussions between partners about their feelings, commitment levels, and future together. The outcome can impact both individuals' emotional well-being and the direction of the relationship. Additionally, it can influence their social circles and how they interact with friends and family regarding their relationship status.

Qualitative is the grouping of things based on their qualities. Quantitative is based off of the quantity, or amount there is, of something.

Subjective quantitative is when you answer subjectively but through numbers. example... how do you feel about busy shops from a scale of 1-10?
If you want to find the structural efficiency the equation for structural efficiency is: maxmum mass the structure can withstand divided by the structure mass.

Quantitative techniques use procedures that focus on objective measurements in order to draw conclusions about research subjects. Some of these methods include polls, surveys and questionnaires.

Quantitative physical properties are measurable characteristics of a substance, such as density, mass, volume, and temperature. These properties can be expressed as numerical values and often involve units of measurement. Quantitative physical properties help define and distinguish different substances based on their specific characteristics.
