N2  - "For junior secondary students, this program covers statistics and simple statistical manipulation as applied in everyday life - in this case, an ice cream vendor keen to build customer profiles. It covers graphical representation of data, including pictographs, bar and column graphs, circle graphs and scatter plots. Also examined is recording data in frequency tables, the construction of frequency histograms and frequency polygons from frequency tables. Three different methods of stating average results are covered - mean, median and mode. Finally, interquartile ranges, box and whisker plots are looked at, with the aim of helping our ice cream vendor choose the most appropriate music for her customers as she sells her wares."-- Back cover
