Question 7

Categories

Answer 7

groups formed according to shared attributes

Question 8

statistics

Answer 8

the collection, analysis, interpretation and presentation of information in a numerical format

Question 9

Name the stages of the data cycle

Answer 9

1. Problem and question
2. Collect and organise data
3. Represent data
4. Analyse and interpret data

Question 10

What occurs during the first stage of the data cycle?

Answer 10

A problem is described and a question is asked

Question 11

What questions can be asked to help you determine a plan for the problem and question?

Answer 11

• 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?

Question 12

What occurs in the second stage of the data cycle?

Answer 12

Information is collected and organised (Recording data)

Examples:
- tables
- lists
- sorting objects (cluster graph)

Question 13

What occurs in the third stage of the data cycle?

Answer 13

The collected data is organised into a format that best showcases your information.

Examples:
- pictographs
- dot plots
- bar graphs

Question 14

What occurs in the final stage of the data cycle?

Answer 14

The data is read and used for exploration and reasoning.

Question 15

What are the ways in which data can be read?

Answer 15

• 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)

Question 16

Example of a question reading between the data

Answer 16

• How many more..?

Question 17

What is the purpose of including data handling in the mathematics syllabus for the foundation phase?

• provide learners with the opportunity to use data to make decisions
• provide learners with the opportunity to answer questions and understand situations

Question 18

What is involved in reading the data?

Answer 18

finding information explicitly in the representation

Question 19

What does reading between the data involve?

Answer 19

-interpreting mathematical relationships
- comparing

Question 20

What is involved in reading beyond the data?

Answer 20

extending and predicting

Question 21

What is involved in reading behind the data?

Answer 21

connecting the data to the context

Question 22

What two skills do learners need to develop to be able to interpret data?

Answer 22

• read information directly from representations
• compare information in representations

Question 23

What is a list?

Answer 23

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

Question 24

What is a tally chart?

What is a table?

Answer 25

A table has rows and columns for the information.

Arepresentation which organises information using rows and columns.

Question 26

What is a bar graph?

Answer 26

A bar graph involves categories and counts of the number of people or things in a category
(frequency).
