Elements and Performance Criteria

Range description
Data collection may be based on a sampling regime followed by an operator or collected automatically
Data collection may include collecting samples and taking measurements
Data analysis typically involves use of computer programs but may also be carried out manually

Ability to:
Identify and collect required data
Retrieve/access data. This may require use of computer programs to access and analyse data. The operator must be able to locate the relevant information or screens to collect and analyse the data
Apply basic statistical analysis techniques to meet work requirements. This typically includes plotting data on charts such as run or control charts and identifying variation according to given limits
Interpret data to identify trends. This may be demonstrated manually or using a computer program
Determine when corrective action is required. This may include identifying upper and lower control limits (and warning limits where relevant)

Knowledge of:
Data sampling method. This requires an understanding of the nature of the sample on which data is based and the reasons for different sampling requirements that may apply in a given situation
Concept of variation. This includes an understanding of the difference between common and special causes of variation and consequent options for reducing variation and remaining within a given range. It also includes a basic understanding of the purpose and process of establishing targets and limits
Concept of standard distribution/standard deviation
Methods used to analyse statistical data. This includes methods to determine the average, median and mean, and what these measures indicate

Relationship with other standards
Pre-requisite units

The pre-requisite for this unit is:

FDFCORBM2A Use basic mathematical concepts
Co-assessment of related units
This unit should be assessed together with core units and other units of competence relevant to the function or work role.

Resources required for assessment

Assessment must occur in a real or simulated workplace where the assessee has access to:

Statistical process control data
Related data collection and analysis systems
Calculator
