5. Quality Assurance

As an example, in a measurer evaluation session children were measured by Measurement Teams and the data recorded and compared.

The data demonstrate that errors can occur in a setting with motivated measurers. The errors were in three categories. There was a measurement error in infant length, an error in reading the scale, and an error in calculating age.

 

Example 1
