Fascinating Fact:
Data loggers can record readings over time, like temperature, light, or sound levels, without someone watching all the time.
In KS3 ICT, data capture is about choosing the best way to collect information and reduce mistakes. You might use forms, scanners, sensors, or manual entry, then apply checks like validation to keep the dataset reliable for analysis.
Key Terms
- Input device: Hardware used to enter data into a computer, such as a keyboard, scanner, microphone, or barcode reader.

- Sampling: Collecting data from part of a group to represent the whole, which can save time if the sample is fair.
Frequently Asked Questions (Click to see answers)
What does data capture mean in ICT?
In ICT, data capture means collecting data and entering it into a computer system. This can be done by people typing, by scanning, or by using sensors that gather readings automatically.
What is the difference between validation and verification?
Validation checks whether data is sensible and in the correct format, such as a range check for age. Verification checks whether the data was entered correctly, such as double entry to spot typos.
What is a data logger used for in data capture?
