Application

This unit of competency defines the skills and knowledge required to interpret and construct graphs and charts from given or determined data, and perform basic statistical calculations.

Graphs and charts apply to information from various work contexts, quality processes, production and market trends and other engineering applications and a range of devices are used to assist with calculations.

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

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

obtaining and interpreting data presented in graphical form and analysing the emerging trends indicated by the data

constructing graphs to scale for which the graph is intended and labelling the axis appropriately

constructing graphs to suit the job requirements

performing basic statistical calculations, including mean, median and mode and determining from that data the standard deviation

undertaking numerical operations, geometry, calculations and formula for using graphical techniques and performing simple statistical computations

applying standard deviation to process improvement techniques in which error rates are mathematically calculated and recorded

checking performance to specifications.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures

characteristics of straight line, parabolic and hyperbolic curves

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

trends 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

meaning of the terms mean, median and mode

meaning of the term standard deviation

significance of 1, 2 and 3 sigma limits.

Assessment Conditions

Assessors must:

have vocational competency in using graphical techniques and performing simple statistical computations at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Foundation Skills
