The University's Summer Data Competition, in partnership with analytics company Purple Seven and Starcount, was judged by Clive Humby, the data scientist behind the Tesco Clubcard loyalty card.
It was aimed at higher education students, in particular those studying maths, statistics and computing.
The winners, Alvis HT Tang and James Clough for their Olympic Games analysis, and Jason Cole for his property price dataset, will receive £3,500 and mentoring from Tesco Clubcard pioneer Clive Humby.
Humby, who is currently chief data scientist at Purple Seven and Starcount, said: "Through this initiative we have been able to champion the next generation of data scientists, many of whom will go on to shake up industries through their ability to analyse information. I look forward to seeing what they achieve in the future.
