Like any other tool in software, analytics dashboards are abstractions. They allow data scientists, analysts, developers, and statisticians to make it as easy as possible for non-experts and peers to gain insights from data. This allows everyone to collect important data and business intelligence without having to put in the additional effort usually required for collecting those insights in the first place.
For those, like me, without a strong understanding of statistics, this means not having to pour over a textbook for a few months just to figure out if a trend is significant or not. For others, this means not having to repeat the same process of collection, processing, cleaning, and analysis to acquire the same insights.
