A supervisor at a small hospital wants to ensure that the number of errors in the hospital's medical records remains in control. The supervisor records the total number of medical records that are filed each day and the number of records that are incomplete or inaccurate (defectives).
Because the data are counts of defectives, you can use this data to demonstrate P Chart Diagnostic and Laney P' Chart.
|Defectives||The number of incomplete and inaccurate records that are filed each day.|
|Total Records||The total number of records that are filed each day. This column contains the subgroup sizes.|
