A first look at the diagram - would indicate 2 possible areas where the defects in measurement could arise from - these are the areas of the 2 circles which are not part of the true assessment area indicated. Refer the diagram below:

The area of the circle of actual performance which has been over looked by the evaluator is essentially a deficiency in the measurement itself. This is called Deficiency Problem.
The area of the circle of measured performance which has been outside the true-assessment area could have two sorts of problems:
The area of the circle of measured performance which has been outside the true-assessment area could have two sorts of problems:
- The reliability of the measurement
- The validity of the measurement
We shall explore these in detail in the next byte.
