Data

Australian national curriculum learning map

Answer yes/no questions to collect information
Choose simple questions and gather responses
Represent data with objects and drawings where one object or drawing represents one data value.
Describe the displays Identify a question of interest based on one categorical variable.
Gather data relevant to the question
Collect, check and classify data
Create displays of data using lists, table and picture graphs and interpret them
Identify questions or issues for categorical variables. Identify data sources and plan methods of data collection and recording
Collect data, organise into categories and create displays using lists, tables, picture graphs and simple column graphs, with and without the use of digital technologies
Interpret and compare data displays
Select and trial methods for data collection, including survey questions and recording sheets
Construct suitable data displays, with and without the use of digital technologies, from given or collected data.
Include tables, column graphs and picture graphs where one picture can represent many data values
Evaluate the effectiveness of different displays in illustrating data features including variability
Pose questions and collect categorical or numerical data by observation or survey
Construct displays, including column graphs, dot plots and tables, appropriate for data type, with and without the use of digital technologies
Describe and interpret different data sets in context
Interpret and compare a range of data displays, including side-by-side column graphs for two categorical variables
Interpret secondary data presented in digital media and elsewhere
Identify and investigate issues involving numerical data collected from primary and secondary sources
Construct and compare a range of data displays including stem-and-leaf plots and dot plots
Calculate mean, median, mode and range for sets of data.
Interpret these statistics in the context of data
Describe and interpret data displays using median, mean and range
Explore the practicalities and implications of obtaining data through sampling using a variety of investigative processes
Investigate the effect of individual data values , including outliers, on the mean and median
Explore the variation of means and proportions in of random samples drawn from the same population
Investigate techniques for collecting data, including census ,sampling and observation. Identify everyday questions and issues involving at least one numerical and at least one categorical variable, and collect data directly from secondary sources
Construct back-to-back stem-and-leaf plots and histograms and describe data, using terms including ‘skewed’, ‘symmetric’ and ‘bi modal’
Compare data displays using mean, median and range to describe and interpret numerical data sets in terms of location (centre) and spread Investigate techniques for collecting data, including census, sampling and observation
Determine quartiles and interquartile range
Construct and interpret box plots and use them to compare data sets
Compare shapes of box plots to corresponding histograms and dot plots
Use scatter plots to investigate and comment on relationships between two numerical variables
Investigate and describe bivariate numerical data where the independent variable is time
Evaluate statistical reports in the media and other places by linking claims to displays, statistics and representative data
Calculate and interpret the mean and standard deviation of data and use these to compare data sets
Use information technologies to investigate bivariate numerical data sets. Where appropriate use a straight line to describe the relationship allowing for variation
