Ashley has correctly drawn a bar and column graph and determined a suitable scale but there is some confusion in the labelling. The measurements are accurate but no explanation has been provided for transferring the 1:1 scale on the picture graph to the 1:10 scale on the column graph. Ashley has interpreted the graphs and made generalisations but would benefit from more than one method of showing information and from indicating how many students were surveyed. This work sample demonstrates characteristics of work typically produced by a student performing at grade C standard at the end of Stage 3.
