The information from an experiment that can be assigned a number or a quantity is referred to as quantitative data. This type of data allows for measurable comparisons and statistical analysis, making it suitable for graphical representation. Examples include measurements like height, weight, temperature, or time, which can be plotted on graphs to visualize relationships or trends in the data.
A variable is assigned to represent an unknown quantity.
Ø In chemistry, algebra can be used to calculate the quantity of a substance required in an experiment. Also, it is used to calculate the quantity of various substances formed in an experiment. Problems of Mole concept are soved on this basis only.
accurate values of the quantity that you wanna measure using certain properties of it.
VARIABLE. When this variable has a fixed number assigned to it and does not change, it is called a "fixed variable".
The variable that you can manipulate in the experiment is always the independent variable. The quantity that changes as a result of your manipulation is the dependent variable.

weighted average is an average in which each quantity to be averaged is assigned a weight. These weightings determine the relative importance of each quantity on the average.

The quantity being tested in a chemistry experiment is typically referred to as the independent variable. This is the variable that the chemist deliberately changes or manipulates to observe how it affects other variables in the experiment. The dependent variable, on the other hand, is the variable that is being measured or observed and is influenced by the changes in the independent variable.

A scalar quantity is a quantity that is ignorant of direction. Scalars have only magnitude, such as temperature or distance, and do not have associated direction information.
