In trying to reduce the variance, the analyst runs and reruns the data, but cannot resolve the problem. In frustration, he consults a colleague, asking what she thinks might be going on with his data. She immediately concurs with his outlook—that is, if we were to stick with the officially reported GDP per capita data, Nestlé would wisely would postpone expanding into many of these countries.
