Using Histograms and Polygons - Tai : Grade Commentary
Tai has demonstrated basic knowledge and understanding of histograms and polygons. The frequency column has been correctly completed but the polygon has been inaccurately drawn and an incorrect method appears to have been used to calculate the median. No understanding of the relationship between the median and the mean has been demonstrated.
