This weeks targets To interpret and construct tables

This week’s targets To interpret and construct tables, charts and diagrams (including bar charts, pie charts and pictograms) To find the mean, median, mode and range for grouped and ungrouped data To construct and interpret diagrams for grouped discrete data and continuous data, i. e. histograms with equal and unequal class intervals and cumulative frequency graphs, and know their appropriate use To interpret, analyse and compare data through methods including using box plots & lower and upper quartiles.
