As data is refreshed and updated, changes can happen through upstream processes that put it at risk of not maintaining the intended quality. By analyzing the historical report snapshot, you can identify areas for improvement, implement changes, and measure the effectiveness of those changes.

For example, researchers from Berkeley used mobile data to predict poverty and wealth of individuals or microregions in Rwanda at a time when measuring poverty in Africa remains a challenge. In 2012 , only 25 of the region’s 48 countries had conducted at least two surveys over the past decade to track poverty.

Of course, exploratory analysis of big unintentional data puts us squarely at risk for these types of mistakes. But this does not mean that the slice will continue to exhibit an extreme value on this measurement in the future. Controlling the Type I error necessarily comes at the expense of increasing the risk of a Type II error.
