A person or thing that averages; in mathematics or statistics, something that calculates or determines an average.
From average plus -er (agent suffix, meaning one who does something). Became common in English as mathematics and data analysis became more important in business and science.
In investing, an 'averager' is someone who uses 'dollar-cost averaging'—buying more when prices drop, less when they rise, to smooth out the chaos of the market. It's a remarkably calm strategy that fights human panic with mathematics.
