This unit covers interpreting and constructing graphs and charts from given or determined data, and performing basic statistical calculations.

Unit details

Study level:
Vocational and further education (TAFE)
Unit code:


MEM12024A - Perform computations


Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - 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, and; - undertaking numerical operations, geometry and calculations/formulae within the scope of this unit.Students will also be expected to demonstrate the following knowledge: - 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. and; - safe work practices and procedures.
