11 Nokia is the world’s leader in cell phones. At the Consumer Electronics Show, Nokia president and CEO, Olli-Pekka Kallasvuo, discussed the company’s strategy for reaching the world’s developing markets. He wants Nokia to “do good business and do good at the same time.” The company’s program, “Calling All Innovators,” aspires to change people’s lives through mobile phones. He described a contest called the “Nokia Growth Economy Venture Challenge”

that provides $1 million in funding to a company that create products that improve people’s lives. He hopes the venture will promote upward mobility to cell phone users in markets where the average income is less than $5 a day. This year’s theme is “Connecting Apps That Make a Difference.” What multivariate technique or combination of techniques would you use to investigate mobile applications that, when connected, improve quality of life?
