This aspect of digital technologies has strong connections to the Mathematics learning area and can be integrated to make learning more meaningful. Connections to other relevant learning areas are also indicated where applicable.
At this level we include numeric data which includes data counted in whole numbers, such as numbers of people, and data that is continuous, such as height or weight. Another form of data is categorical data. This data is often a word or a symbol that can be ranked or ordered, such as a temperature scale from cold to hot, and those data that cannot be ranked or ordered, such as eye colour, gender or types of pets. Our focus in Digital Technologies is how to work with the data in digital form.
It's worth pointing out that in Digital Technologies, representing data refers to the way data is symbolised, visually treated or provided in audio. For example, at this level data about animals may be represented as images of each animal, emotions may be represented as emojis, and weather data may be represented as icons for wind, rain or describing the amount of sunshine. Presentation of data deals with the format it may be presented in, such as in a table, T-chart or Y-chart, a picture graph or a bar graph.
We may collect data through observations, by survey or from other sources. Data often comes to us unorganised, so the first step is to sort the data by common characteristics or attributes; then arrange the data to help make sense and look for patterns; and finally present the data visually.

Numeric data includes data counted in whole numbers such as numbers of people and data that is continuous such as height or weight.
Categorical data is often a word or a symbol that can be ranked or ordered, such as a temperature scale from cold to hot, and those data that cannot be ranked or ordered, such as eye colour, gender or types of pets.
Glyphs are a fun and colourful way for students to collect, explore and sort data about themselves and their classmates using a range of themes. A glyph is a pictorial representation of data, and can be created using drawings, collage or digital artworks.
Rebus stories use pictures or symbols to represent words or parts of words.
Musical notes can be represented in different ways. The rhythm and beat can be represented visually using colours and shapes. Colours can be used to represent particular notes. The block shape can represent the time signature and length of note.
Data can be graphed visually and presented as a chart, for example, a column graph.
When counting up physical items these can be sorted and organised into columns and presented as a column graph.
