Students will use mental mathematical strategies to find the average of a set of numbers.
Acquire, validate and represent data for nominal and ordinal categorical and discrete numerical variables to address a question of interest or purpose using software including spreadsheets; discuss and report on data distributions in terms of highest frequency (mode) and shape, in the context of the data
Interpret and compare data sets for ordinal and nominal categorical, discrete and continuous numerical variables using comparative displays or visualisations and digital tools; compare distributions in terms of mode, range and shape
Construct displays, including column graphs, dot plots and tables, appropriate for data type, with and without the use of digital technologies
Interpret and compare a range of data displays, including side-by-side column graphs for two categorical variables
Calculate mean, median, mode and range for sets of data. Interpret these statistics in the context of data
Construct displays, including column graphs, dot plots and tables, appropriate for data type, with and without the use of digital technologies
Construct, interpret and compare a range of data displays, including side-by-side column graphs for two categorical variables
Pose and refine questions to collect categorical or numerical data by observation or survey
Describes and represents mathematical situations in a variety of ways using mathematical terminology and some conventions
Gives a valid reason for supporting one possible solution over another
Uses appropriate methods to collect data and constructs, interprets and evaluates data displays, including dot plots, line graphs and two-way tables
Constructs graphs using many-to-one scales
Interprets data displays, including timelines and line graphs
