Using Histograms and Polygons - Chandra : Grade Commentary
Chandra has demonstrated basic knowledge and understanding of histograms and polygons. The mean and median have been calculated using standard procedures and some working has been provided as justification but no conclusions have been drawn. There is some confusion about frequency and cumulative frequency, and the ogive is incorrect.
