Ensuring Accurate Data Capture

Why is data accuracy important in data capture devices?

• It ensures faster data processing.

• It reduces the risk of errors in decision-making.

• It increases the cost of data storage.

• It allows for more complex data structures.

Which of the following is a common data validation technique?

• Data encryption

• Range check

• Data compression

• Data mining

What is the primary purpose of data validation?

• To increase data redundancy

• To ensure data is accurate and reasonable

• To enhance data visualisation

• To speed up data entry

Which of the following is NOT a characteristic of data capture devices?

• Portability

• Data accuracy

• High power consumption

• User-friendliness

What is a key benefit of using data capture devices with high data accuracy?

• Increased data redundancy

• Reduced need for data validation

• Improved decision-making

• Higher data storage costs

Which data validation technique checks if data falls within a specified range?

• Format check

• Range check

• Consistency check

• Uniqueness check

How does data validation contribute to data accuracy?

• By increasing data entry speed

• By ensuring data is entered in a consistent format

• By reducing the need for data storage

• By allowing more data to be captured

Which of the following is an example of a data capture device?

• Printer

• Scanner

• Monitor

• Speaker

What is the role of a format check in data validation?

• To ensure data is within a certain range

• To verify data is in the correct format

• To check for duplicate data entries

• To encrypt sensitive data

Why is it important to control data input in data capture devices?

• To increase the speed of data entry

• To ensure data is accurate and reliable

• To reduce the cost of data capture devices

• To allow for more complex data analysis
