Questions from this subtopic
Each one with the model answer underneath.
- 1
What is big data?
Model answer
Big data describes data sets so large, fast-changing or varied that ordinary software cannot process them. Specialist tools are needed to store and analyse the data.
- 2
What are the three Vs of big data?
Model answer
The three Vs are volume, velocity and variety. Volume is the amount of data, velocity its speed of arrival, and variety its range of formats.
- 3
What do veracity and value add to the three Vs of big data?
Model answer
Veracity is how accurate and trustworthy the data is. Value is whether analysing the data produces useful benefits for the business.
- 4
Give three sources of big data for a business.
Model answer
Online sales transactions generate big data. Website browsing records and social media posts are further sources.
- 5
How can big data help an audit firm?
Model answer
Audit software can test every transaction in a client's records rather than a sample. Unusual patterns that suggest error or fraud then stand out more reliably.
- 6
How can a law firm use big data in litigation?
Model answer
Software can search millions of emails and documents for relevant evidence. A review that once took weeks can be done in days.
