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 explore the layers of computer systems from programs to the physical components that store and execute these programs. They will discover the fundamental binary building blocks that make up computer systems and how systems are evolving for developments such as AI.
Lesson Summary
You will learn to describe data science and explain how data is used to make decisions.
Key Notes
- Data science is used to make smarter decisions.
- Data scientists analyse data to find patterns and discover useful information.
- Data can be cleaned and organised to make it more useful.
- Data can be biased if it doesn't represent everyone fairly.
Vocabulary To Learn
- analyse: to look at something carefully to understand it better
- data pattern: a recurring trend, relationship, or structure found within a set of data
- data cleaning: the process of detecting and correcting, or removing, corrupt or inaccurate data from a data set
- data bias: when data is unfair or unbalanced, which can lead to wrong or unfair results
Common Mistakes To Avoid
- Data science is just about collecting loads of data.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Data science is used to make smarter decisions. Data scientists analyse data to find patterns and discover useful information.
2. Define this computing term and give one practical example. 'analyse'
to look at something carefully to understand it better. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Data science is just about collecting loads of data. Correction: Data science isn't just about gathering data, it's about understanding data and using it to make decisions or discoveries.
