This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will discover how to use data to investigate problems and make changes to the world around them. Pupils will be exposed to both global and local data sets and gain an understanding of how visualising data can help with the process of identifying patterns and trends.
Lesson Summary
You will learn to analyse visualisations to draw conclusions and report findings.
Key Notes
- Graphs and charts can be used to visualise data and make it easier to understand.
- By looking at visualisations, patterns can be spotted, trends can be seen over time.
- Unusual data (outliers) can be identified and removed.
- A report can be used to present conclusions and findings from data analysis.
Vocabulary To Learn
- visualisation: a variety of techniques used to illustrate a problem and/or its solution to make it easier to understand
- conclusion: a judgement or decision reached by reasoning or using data
Common Mistakes To Avoid
- A visualiation will always tell you the information you need to know.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Graphs and charts can be used to visualise data and make it easier to understand. By looking at visualisations, patterns can be spotted, trends can be seen over time.
2. Define this computing term and give one practical example. 'visualisation'
a variety of techniques used to illustrate a problem and/or its solution to make it easier to understand. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: A visualiation will always tell you the information you need to know. Correction: You may need to refine or collect more data to create visualisations which answer your questions effectively.
