Attribute charts' P (proportion) chart
In this recipe, we will use a proportion chart to track events or defective items out of a total.
This data looks at the number of breaches within an accident and emergency department. The hospital has a target, according to which patients arriving at the accident and emergency ward must be seen by a doctor within four hours. A breach is classified as a patient who has not been attended to within this time. The dataset that we are using is organized into columns for ease of entry. Total attendance at accident and emergency is listed in row 1 and breaches are listed in row 2.
We will need to transpose the data into a new worksheet to put it back into a column format, before generating the P chart.
