Represent numerical values.

Constants are numerical values which are fixed but which may or may not be known. Variables are also numerical but may take a range of values. If a variable appears in an equation or inequality), it may be possible to solve the equation to ascertain the value of the variable.

In statistics numerical data is quantitative rather than qualitative.

Ratios ARE numerical.

A numerical expression uses numbers and operations. It also has an equal sign. An algebraic expression uses variables and operations. Unlike a numerical expression it does not have an equal sign.

In statistics numerical data is quantitative rather than qualitative.

Physical constants are used for two main reasons. First, the quantitative predictions depend on the numerical values of the constants. An accurate knowledge of their values is therefore essential to achieve an accurate quantitative description of the physical universe. Second, the careful study of these constants can in turn test the overall consistency and correctness of the basic theories of physics themselves.

Precision of a measurement represents the numerical values which represent the dimensions of the instrument measured more accurately.Precised values are nearer t accuracy with negligible error.

Constants in the sense you mean are different to mathematical constants. They usually refer to a system in which two values are proportionate and so are of the units associated with the system.
