A NUMERICAL VARIABLE is an INSTRUMENT VARIABLE which measures a QUALITY which has for quales (during a TIME INTERVAL) NUMBERS or SCALAR QUALES (a NUMBER + a UNIT OF MEASURE). Example 1: The NUMERICAL VARIABLE ‘FCSRT-IR-3-1v3' of the INSTRUMENT ‘Free and Cued Selective Reminding Test with Immediate Recall 16-item-version-(FCSRT-IR)’ measures the QUALITY ‘Total number of words correctly retrieved on the three successive trials’ which has for quales NUMBERS. This NUMERICAL VARIABLE has for minimum numerical value 0 and has for maximum numerical value 48. Example 2: The NUMERICAL VARIABLE of the INSTRUMENT ‘Rey-Osterrieth-Complex-Figure-Test-(CFT)-Copy-administration’ measures the QUALITY ‘length of time needed by the subject to copy the figure’ which has for quales SCALAR QUALES. The test is not timed, but the length of time needed to copy the figure is observed, and the average time is about 180 seconds. This NUMERICAL VARIABLE has for minimum scalar value 0 second and has for maximum scalar value a SCALAR QUALE chosen by the examinator beyond 300 seconds.
