Indirect Drivers are states, experiences, or circumstances that affect the measurement of interest, but may have a less straightforward relationship with the variable. For example, if NPS is the measurement of interest (or Dependent Variable), the perceived “niche” of the industry, the state of the economy, the demographic makeup of the respondent’s household, or the relevance of the product/service at this point in the respondent’s life could all be Indirect Drivers of their NPS rating.
