Elements of Competency Performance Criteria              
Element: Read and construct graphs from given or determined data
  • Complex information is extracted from graphical representation.
  • Data is analysed with respect to emerging trends.
  • Graphs are constructed as required from data and drawn with respect to scale and accepted method.
  • Significant features of graphical representation are understood such as limit lines, gradients (straight line graphs), intercepts, maximum and minimum values.
  • A wide variety of graphs are constructed as required including histograms, control charts, straight line graphs and parabolic graphs.
       
Element: Perform basic statistical calculations
  • Mean, median and mode are calculated from given data.
  • Standard deviation is calculated.
  • Application of standard deviation and limits to process improvement techniques is understood.
       


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.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to use graphical techniques and perform simple statistical computations. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with using graphical techniques and performing simple statistical computations or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment


Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)


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.

Required skills

Look for evidence that confirms skills in:

obtaining required information by interpreting data presented in graphical form

determining the trend(s) indicated by the data presented in graphical form

constructing graphs to scale

labelling the axes appropriately

selecting scales appropriate to the purpose for which the graph is intended

constructing histograms, control charts, straight line and parabolic graphs

determining for a given set of data the mean, median and mode

determining for a given set of data the standard deviation

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

planning and sequencing operations

checking and clarifying task related information

checking for conformance to specifications

undertaking numerical operations, geometry and calculations/formulae within the scope of this unit

Required knowledge

Look for evidence that confirms knowledge of:

characteristics of straight line, parabolic and hyperbolic curves

procedures for determining the slope/rate of change of a curve

the trend(s) indicated by changes in gradient of a graph

procedures for drawing the line of best fit for the coordinates plotted

standard form of equations relating to straight lines and parabolic curves

gradient, intercepts, maximum and minimum values and limit lines for straight line and parabolic curves

function of control charts

the meaning of the terms mean, median and mode

the meaning of the term standard deviation

the significance of 1, 2 and 3 sigma limits

safe work practices and procedures

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Process improvement techniques

Techniques in which error rates are mathematically calculated and recorded such as three sigma and six sigma

NOTE: This unit gives the underpinning calculation skill for these techniques and does not cover the implementation or use of three or six sigma systems

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.
