Data Handling Flashcards
Data
Information
Comparing
finding a relationship between two items based on a specific attribute
Data collection
recording information collected during observations
Elements
the parts of a set
(not necessarily concrete objects e.g. days of the week)
Classifying
grouping or sorting according to properties such as size, shape, colour etc
Attribute
property of an object/item which can be used to sort it
Categories
groups formed according to shared attributes
statistics
the collection, analysis, interpretation and presentation of information in a numerical format
Name the stages of the data cycle
- Problem and question
- Collect and organise data
- Represent data
- Analyse and interpret data
What occurs during the first stage of the data cycle?
A problem is described and a question is asked
What questions can be asked to help you determine a plan for the problem and question?
- What do I want to find out?
- How will I get the information I need?
- What will I do with the information I collect?
- Who would the information be useful to?
What occurs in the second stage of the data cycle?
Information is collected and organised (Recording data)
Examples:
- tables
- lists
- sorting objects (cluster graph)
What occurs in the third stage of the data cycle?
The collected data is organised into a format that best showcases your information.
Examples:
- pictographs
- dot plots
- bar graphs
What occurs in the final stage of the data cycle?
The data is read and used for exploration and reasoning.
What are the ways in which data can be read?
- reading the data (finding information explicitly in the representation)
- reading between the data (interpreting mathematical relationships– comparing)
- reading beyond the data (extending, predicting)
- reading behind the data (connecting the data to the context)
Example of a question reading between the data
- How many more..?
What is the purpose of including data handling in the mathematics syllabus for the foundation phase?
- to develop citizens who can read and appreciate the value of statistics
- provide learners with the opportunity to use data to make decisions
- provide learners with the opportunity to answer questions and understand situations
What is involved in reading the data?
finding information explicitly in the representation
What does reading between the data involve?
-interpreting mathematical relationships
- comparing
What is involved in reading beyond the data?
extending and predicting
What is involved in reading behind the data?
connecting the data to the context
What two skills do learners need to develop to be able to interpret data?
- read information directly from representations
- compare information in representations
What is a list?
A list is a series of related words, numbers or other items…. A list may or may not be numbered, or organised in some logical way
What is a tally chart?
Tally marks/ lines grouped by five
