Using Histograms and Polygons - Chris : Grade Commentary
Chris has demonstrated basic knowledge and understanding of histograms and polygons. Standard procedures have been used to construct the cumulative frequency polygon and graph the histograms but there are minor inaccuracies with the scale in question 1. Some correct calculations have been performed and the mean has been found, but no conclusions have been drawn and the shape of the graph in question 5 has not been linked to the median or mean. This work sample demonstrates characteristics of work typically produced by a student performing at grade D4 standard at the end of Stage 5.
