Often times getting close to an answer that is approximately correct is better than trying to find the perfect solution. Most real world problems, especially in analyzing data, don't have perfect answers. For example approximations are made all the time in physics, because without these approximations the calculations can't be done. Knowing when to make approximations and what approximations to make is an essential skill for analyzing data.
