Summarize this article for a 10 year old

**Quantitative analysis** is the use of mathematical and statistical methods in finance and investment management. Those working in the field are **quantitative analysts** (**quants**). Quants tend to specialize in specific areas which may include derivative structuring or pricing, risk management, investment management and other related finance occupations. The occupation is similar to those in industrial mathematics in other industries.^{[1]} The process usually consists of searching vast databases for patterns, such as correlations among liquid assets or price-movement patterns (trend following or reversion).

Although the original quantitative analysts were "sell side quants" from market maker firms, concerned with derivatives pricing and risk management, the meaning of the term has expanded over time to include those individuals involved in almost any application of mathematical finance, including the buy side.^{[2]} Applied quantitative analysis is commonly associated with **quantitative investment management** which includes a variety of methods such as statistical arbitrage, algorithmic trading and electronic trading.

Some of the larger investment managers using quantitative analysis include Renaissance Technologies, D. E. Shaw & Co., and AQR Capital Management.^{[3]}
