Application

This unit describes the skills and knowledge required to process and perform calculations on environmental data and present data using simple visualisations.
This unit applies to environmental assistants, environmental officers, environmental technicians and similar roles who are required to retrieve data, perform scientific calculations, interpret and present data in tables, graphs and simple maps and keep accurate records.
The individual will solve problems of limited complexity where the information may not be obvious but is not contradictory and can be determined by direct reasoning. A calculator or computer and software will typically be used but is not required.
No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.

What You'll Learn

1.

  • 1.1 Read and interpret workplace procedures for processing data
  • 1.3 Verify the quality of data using workplace procedures
  • 1.4 Rectify errors in data using workplace procedures

2.

  • 2.1 Calculate statistical values for given data
  • 2.3 Ensure calculated quantities are consistent with estimations and expectations
  • 2.4 Report all calculated quantities using the appropriate units and correct number of significant figures

3.

  • 3.1 Present data visually including use of clearly labelled tables, charts and simple maps
  • 3.3 Report all data using the appropriate units and number of significant figures

4.

  • 4.1 Compare data with reference values or expected ranges
  • 4.3 Interpret significant features of graphs, including gradients, intercepts, maximum and minimum values, and limit lines

5.

  • 5.1 Transcribe information accurately
  • 5.3 File and store workplace records in accordance with workplace procedures
  • 5.4 File all reference documents logically and keep them up-to-date and secured
  • 5.5 Maintain the security and confidentiality of data and documentation in accordance with workplace requirements

Assessment Requirements

Knowledge Evidence

There must be evidence the candidate has knowledge of:
• scientific and technical terminology relevant to job role
• procedures for coding, entering, storing, retrieving and communicating data
• international system of units (SI)
