How can you compare figures on a consistent basis?
The situation
Fictional scenarioWhat is getting in the way
These are separate fictional practice figures. Time, group and target references use the same arithmetic but support different interpretations. Record the definitions. Relative change is undefined when the baseline is zero.
Compare one value against different references
Check the population, period, units and definitions before interpreting the numbers. Example calculations do not establish causes or effects.
Compare one value against different references
| Measure | Check |
|---|---|
| Current value | A nonnegative quantity; specify the unit in the definitions. |
| Reference value | Use the same unit as the current value; blank is not zero. |
| Scope, periods, units and definitions | Record comparability and any sample changes. |
When the situation changes
- Time reference
- State adjacent-period or year-over-year comparison and check window length and definitions.
- Group reference
- Volume differences may reflect scale or work mix, not capability.
- Target reference
- The gap shows distance from the target; it does not establish that the target is appropriate or approved.
