Which statement about factors in a media mix model is NOT typical?

• A. Reach
• B. Frequency
• C. Weather
• D. Attribution

Answer: (C)

In media mix modeling, you focus on factors that describe how advertising exposure and spend translate into outcomes, and how credit for those outcomes is distributed across channels. Reach measures how much of the audience you’re exposing to the message, and Frequency tracks how many times they see it. Attribution is about assigning the observed results to the different channels so you can see which ones contributed most. Weather, while it can affect demand in some cases, isn’t a standard driver in the typical MMM framework because it doesn’t directly describe ad exposure or the channel’s effectiveness. It might be included as a one-off covariate in highly specialized analyses for weather-sensitive categories, but it isn’t a core, routinely modeled factor like reach, frequency, or attribution.
