Interrogate and analyse statistical data

Assessment tool

Version 1.0
Issue Date: March 2024


This unit describes the skills required to apply techniques to analyse statistical data. It includes planning the analysis, applying statistical concepts and processes, determining strengths and weaknesses of the analysis and producing further statistics.

This unit applies to those working in generalist and specialist roles within the public sector.

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 seeking advice as required, performing complex tasks in a range of familiar contexts.

No licensing, legislative or certification requirements apply to unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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. Plan analysis

1.1 Choose analysis and descriptive tools and techniques appropriate to the nature of the information and the required outcome.

1.2 Determine priority of data to be interrogated in consultation with suitably qualified people, and organise work.

1.3 Reflect an understanding of the nature of the program or activity from which the data is obtained in the analysis of material.

1.4 Reflect an understanding of the way in which the data is structured in the system in the analysis.

1.5 Reflect the likely statistical indicators of the results in the analysis.

2. Apply statistical concepts and processes

2.1 Use software to retrieve data and present it in the required format.

2.2 Perform quantitative or qualitative analyses to obtain required outcomes.

2.3 Use analysis and descriptive tools and techniques appropriately given the nature of the information and the required outcomes.

2.4 Express preliminary results in accordance with the required detail, format and timeframe of the project.

2.5 Perform analysis.

3. Determine strengths and weaknesses of analysis

3.1 Identify sources of error and describe as required.

3.2 Identify and describe limitations in the methodology as appropriate.

3.3 Verify the conduct and results of analysis by a suitably qualified person.

4. Produce further statistics

4.1 Calculate summary statistics from the given dataset as required.

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.

applying legislation, regulations and policies relating to statistical analysis

using at least one statistical analysis package

utilising the most relevant data capture (software)

using GIS and web mapping/web GIS tools to access and/or manipulate data

using a spreadsheet or database package for data analysis

using statistical tools to collect, store and analyse data

calculating growth rates and percentage change over time

applying analytical problem solving

communicating statistical concepts

being able to "listen" to data needs and use appropriate statistics, including mean, median, mode, standard deviation

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.

public sector legislation including WHS and environment, regulations, policies, procedures and guidelines relating to statistical analysis

the limitations of the data and statistics used

the concept of variation

changes occurring over time

relevance of the calculated statistics and the metadata associated with these statistics

the importance of selecting the appropriate statistical analysis

the method of selecting the appropriate statistical analysis

sources of expertise within the organisation

This unit contains no specific industry-mandated assessment conditions. Guidance on suggested and recommended conditions and methods can be found in the Implementation Guide.

Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.


Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
