variable, Math - symbol
The quantity or characteristic measured or computed. The corresponding numerical value may be taken for statistical handling; it may, for example, be a measured value or result.
Comment:
Note that statistical usage employs capital letters for random variables, and lower case for particular or observed values. In circumstances where the choice of 'Math - symbol' as the symbol may cause confusion, another symbol may be used.
