3. A teacher records that 18 students like apples. What does the number 18 represent? (A recorded number is a fact collected during an observation or survey.)
   A computer program · An internet connection · Collected data · Computer hardware
4. What is the main purpose of analysing data? (Analysis helps us understand what the collected facts show.)
   To discover patterns and understand results · To erase all collected facts · To make data meaningless · To stop people asking questions
5. Which statement is an example of information? (Information gives meaning to collected facts.)
   A blank survey sheet · An unlabelled list of numbers · Mango, apple, banana, orange · Most students in the class prefer mangoes
6. What does an AI system use to learn patterns? (AI learns from examples provided in its data.)

7. A smart camera identifies a cat in a photograph. Which ability is it using? (AI can analyse visual features to identify objects.)
   Measuring the weight of the camera · Playing a musical instrument · Printing a document · Recognising patterns in image data
8. Why should we use accurate and relevant data when training AI? (The quality of training data can affect the quality of AI results.)
   To guarantee that AI never makes mistakes · To help AI produce more reliable results · To prevent AI from learning · To remove the need for human judgement
9. Which of these is an example of audio data? (Audio data contains sounds that we can hear.)
   A drawing of a bird · A picture of a bird · A recording of a bird singing · A written description of a bird
10. A student groups ladybugs by their body colour. Which step of data analysis is the student performing? (Grouping similar observations helps make data easier to compare.)

11. A weather app predicts rain using weather records. What is the app doing? (AI can use patterns in past data to help predict future conditions.)
    Creating a handwritten letter · Recording a song · Sorting school stationery · Using data to make a prediction
12. What may happen if an AI system is trained using incorrect data? (AI results can be affected by the quality of the data used for learning.)
    It may produce inaccurate results · It will always become correct · It will automatically fix every error · It will never need data again
