   • Check data to identify transcription errors or atypical entries
   • Rectify errors in data using workplace procedures
2. Calculate simple scientific quantities
   • Calculate simple scientific quantities using given formulae and data
   • Ensure calculated quantities are consistent with estimations and expectations
   • Report all calculated quantities with appropriate precision and units
3. Present data
   • Present data accurately in tables, charts and graphs using given formats and scales
   • Recognise and report obvious features and trends in data
4. Store and retrieve data

   • Maintain workplace confidentiality standards

Range Statement

This field allows for 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.
Standards, codes, procedures and/or workplace requirements	Standards, codes, procedures and/or enterprise requirements include the latest version of one or more of: relevant Australian and international standards, such as the international system of units (SI) and its application national measurement regulations and guidelines
Data	Data includes: worksheets, spreadsheets or databases linked to information management systems results of observations, tests and measurements, or surveys graphs, tables and control charts semi quantitative observations expressed on a scale e.g. 1 to 4 or + to ++++
Work health and safety (WHS) and environmental management requirements	WHS and environmental management requirements include: · complying with WHS and environmental management requirements at all times, which may be imposed through state/territory or federal legislation. These requirements must not be compromised at any time · applying standard precautions relating to the potentially hazardous nature of samples accessing and applying current industry understanding of infection control issued by the National Health and Medical Research Council (NHMRC) and State and Territory Departments of Health, where relevant
