This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit looks at how a flat-file database can be used to organise data. Pupils will use tools to order and answer questions about data. They will create graphs and charts from their data to solve problems. They will use a real-life database to answer a question, and present their work to others.
Lesson Summary
You will learn to explain that computer programs can be used to compare data visually.
Key Notes
- Charts can be used to visually compare data.
- Charts can be refined by selecting a particular filter.
- Computer-based charts can be edited and refined more easily than paper-based charts.
Vocabulary To Learn
- chart: a way of presenting data graphically
- axis: a line on a chart that shows what the data means
Common Mistakes To Avoid
- All charts made from the same data are equally useful.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Charts can be used to visually compare data. Charts can be refined by selecting a particular filter.
2. Define this computing term and give one practical example. 'chart'
a way of presenting data graphically. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: All charts made from the same data are equally useful. Correction: Some charts might not help answer a specific question, even if they are accurate. Choosing the right chart type and structure matters.
