In what way does experimentation help achieve a best-in-class measurement approach?

Experimentation is crucial for a best-in-class measurement approach because it allows advertisers to validate hypotheses and test insights derived from data. By running controlled experiments (like A/B tests), marketers can isolate variables and determine the true impact of changes, ensuring that decisions are based on empirical evidence rather than assumptions. This leads to more accurate measurement and optimized campaign performance. "By assisting in the collection of multiple data points" is incorrect because while experiments generate data, their primary value in measurement is validation, not just data collection itself. "By driving a macro budget strategy" is too broad; experimentation informs specific tactical adjustments, not necessarily the overarching budget strategy. "By helping assign credit across touchpoints" describes attribution modeling, which is a different aspect of measurement.
