The formula to calculate the Affinity Index (AI) is:
\[ AI = \left( \frac{N}{T} \right) \times 100 \]
Where:
The Affinity Index is a metric used in marketing to measure the likelihood of a certain group of consumers to buy a particular product or service compared to the general population. It helps businesses identify and target specific consumer segments that are more likely to engage with their product or service. The index is calculated by comparing the percentage of a group interested in a product to the percentage of the total population interested in the same product. A score above 100 indicates a higher than average likelihood, while a score below 100 indicates a lower than average likelihood.
Let's assume the following values:
Using the formula to calculate the Affinity Index:
\[ AI = \left( \frac{150}{1000} \right) \times 100 = 15\% \]
The Affinity Index is 15%.
