Application
This unit describes the skills required to analyse data collected during a test and evaluation process. It includes establishing trends and relationships in the data, and establishing the acceptability of the data.
This unit was developed for Defence test and evaluation workers, but is applicable to any individuals who work in this field.
The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.
Those undertaking this unit would work independently or as part of a team, under direct and indirect supervision, use discretion and judgement, and take responsibility for the quality of their output. They would perform complex tasks in a range of contexts.
No licensing, legislative or certification requirements apply to unit at the time of publication.
Elements and Performance Criteria
ELEMENTS | PERFORMANCE CRITERIA |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section. |
1. Perform scientific calculations | 1.1 Ensure consistency of raw data with expectations and reasonable ranges. 1.2 Calculate scientific quantities. 1.3 Determine calculated quantities and estimations. 1.4 Present results using the appropriate units, uncertainties and number of significant figures. |
2. Analyse trends and relationships in data | 2.1 Determine relationships between sets of data. 2.2 Prepare and analyse data to determine if a process is in control. 2.3 Identify possible causes for out of control condition. |
3. Determine variation and/or uncertainty in data distributions | 3.1 Organise raw data into appropriate frequency distributions. 3.2 Calculate statistical properties for ungrouped and grouped data. 3.3 Interpret statistical properties to determine characteristics of sample or population. 3.4 Calculate standard deviations and confidence limits for means and replicates. 3.5 Determine uncertainty in measurements using statistical analysis. 3.6 Determine data acceptability using statistical tests and organisational procedures. |
4. Check for aberrant results | 4.1 Identify results that cannot be reconciled with documentation, testing procedures and/or expected outcomes. 4.2 Determine appropriate actions in consultation with supervisor as required. |
5. Maintain results | 5.1 Store, retrieve and manipulate data following document traceability procedures. 5.2 Present results in an appropriate format. 5.3 Verify entry of data and results. 5.4 Maintain security and confidentiality of data. 5.5 Prepare reports in a format and style consistent with their intended use and organisational guidelines. |
Evidence of Performance
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.
completing mathematical calculations involving fractions, decimals, ratios, proportions and percent
evaluating mathematical formulae
interpreting scientific properties
preparing and interpreting graphs and data
Evidence of Knowledge
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.
characteristics of a valid measurement
procedures for data traceability
procedures for maintaining and filing records, security of data
procedures for verifying data and rectifying mistakes
relevant scientific terminology
sources of uncertainty in measurements
Assessment Conditions
Competency should be assessed in an actual workplace or in a simulated environment, with access to equipment and infrastructure appropriate to the outcome. Competency should be demonstrated over time to ensure the candidate is assessed across a variety of situations.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
