## What is the Methodology of Data Aggregation Techniques?

Data Aggregation Techniques encompass the specific quantitative methodologies employed to combine multiple price points or external variables into a single, usable input for smart contracts. These techniques range from simple arithmetic means to more complex volume-weighted or time-weighted calculations designed to reflect market activity accurately. The choice of technique directly influences the resulting metric's susceptibility to manipulation.

## What is the Computation of Data Aggregation Techniques?

The on-chain computation required to process these techniques must be efficient, as excessive gas usage can render the data feed economically unviable for frequent updates. Developers often optimize these algorithms to minimize computational overhead while maximizing the statistical relevance of the aggregated result. This balance between precision and cost is a constant design constraint.

## What is the Metric of Data Aggregation Techniques?

The output of these techniques serves as a critical metric for derivatives pricing, collateral valuation, and automated execution triggers across the ecosystem. For instance, a time-weighted average price is a specific technique used to generate a benchmark metric that dampens the impact of transient spikes. Understanding the underlying technique provides insight into the metric's behavior under stress.
