A Employee satisfaction survey results

B Marketing spend by channel

Interpreting Marketing Mix Model Results

A marketing mix model shows that TV advertising has a diminishing return effect after a certain spend level. What does this mean?

A TV ads stop working completely after that spend level

B Increasing TV ad spend beyond that level will lead to proportionally smaller increases in sales

C Sales will decrease if TV ad spend increases beyond that level

D TV advertising is ineffective at all spend levels

💡 Hint

Think about what 'diminishing returns' means in everyday life, like eating more food or studying longer.

Diminishing returns means each additional dollar spent on TV ads produces less sales increase than the previous dollar, but it still adds some value.

Comparing Marketing Mix Modeling and Attribution Modeling

Which statement best distinguishes marketing mix modeling (MMM) from digital attribution modeling?

A MMM provides real-time campaign feedback, attribution modeling is only retrospective

B MMM focuses only on digital channels, attribution modeling includes offline channels

C MMM is used exclusively for social media, attribution modeling is for TV ads

D MMM analyzes aggregated historical data across channels, while attribution modeling tracks individual user interactions in digital channels

💡 Hint

Consider the scale and data type each method uses.

MMM uses aggregated data over time to estimate channel effects broadly, while attribution modeling follows individual customer journeys digitally.

Applying Marketing Mix Modeling Insights to Budget Decisions

A company’s MMM results show that digital ads have a high return on investment (ROI) but TV ads have a larger total sales impact. How should the company adjust its marketing budget?

A Cut TV ads completely and put all budget into digital ads because ROI is higher

B Keep the budget the same because changing it will confuse customers

C Increase digital ad spend to maximize ROI but maintain some TV spend to keep overall sales high

D Reduce digital ads and increase TV ads because total sales impact is more important than ROI

💡 Hint

Think about balancing efficiency (ROI) and total sales impact.

High ROI means digital ads are efficient, but TV ads drive large sales volume. A balanced approach optimizes both efficiency and scale.
