Elements and Performance Criteria

1. Identify situations where statistics are used in the workplace
   • Types of statistical representations of data used in the workplace are identified
   • Users of statistical data in the workplace are identified
   • Statistical data representations are matched for applications to monitor work flow, inventory and stock levels, customer surveys, and supplier and market analysis
2. Collect data
   • Purpose of data collection is identified
   • Sources of information are identified
   • Data collection methods are used
   • Mathematical processes are used to arrange data
   • Data collected is checked for accuracy
   • Potential for inaccurate results arising from variables is estimated and described
3. Make calculations to present data for analysis
   • Data collected is represented on graphs as required
   • Calculating equipment and spreadsheets are used to analysis data
5. Interpret trends and patterns from numerical data
   • Non-conforming results outside of the predicted outcome are noted and reasons identified
   • Trends or patterns in data are noted
   • Possible reasons for trends or patterns are generated
   • Potential solutions are identified

Range Statement

Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Range is restricted to essential operating conditions and any other variables essential to the work environment.
Unit context includes:	work health and safety (WHS) requirements, including legislation, building codes, material safety management systems, hazardous and dangerous goods codes, and local safe operating procedures or equivalent work is carried out in accordance with legislative obligations, environmental legislation, relevant health regulations, manual handling procedures and organisation insurance requirements work requires individuals to demonstrate analytical ability, discretion, judgement and problem solving use of statistics within an enterprise is undertaken in accordance with established enterprise procedures and practices work is performed with little external assistance and minimal supervision or direction. The development of modifications may require the assistance and cooperation of others customers may be internal or external
Tools and equipment include:	appropriate computing systems for storage, manipulation, management and presentation of statistical information handheld calculators graphs charts mathematical tables
Personal protective equipment includes:	that prescribed under legislation, regulations and enterprise policies and practices
Information and procedures include:	work procedures/instructions organisation work specifications and requirements benchmarking information and standards legislation/regulations/national and industry codes and practices relevant to the product quality and Australian Standards and procedures

Performance Evidence

Collect, organise and understand information related to multi-trade work instructions and work orders, building and structural plans and safety procedures

Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

Identify materials used in the work process

Follow work instructions, operating procedures and inspection processes to:

minimise the risk of injury to self or others

prevent damage to goods, equipment and products

maintain required production output and product quality

Use general and statistical data representations to explain work processes and/or outcomes

Identify and read graphs, charts, tables and statistical results and interpret general and statistical data accurately

Use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate material requirements

Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems, interpret basic plans and follow safety procedures

Use workplace technology related to the coordination, including communication equipment, time and management aids and other measuring devices

Avoid backtracking, work flow interruptions or wastage

Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
