Marley has demonstrated a basic understanding of the use of graphs to display data. A computer-generated line graph has been selected but the choice has not been justified mathematically. A title has been provided and the axes have been labelled but the graph is an inappropriate choice for the type of information to be displayed. A column graph has been listed as a possible alternative but no understanding of the advantages and disadvantages of the two types of graphs has been shown. This work sample demonstrates characteristics of work typically produced by a student performing at grade D standard midway through Stage 3.
