Final answer:
The Bedford Bagel Shop would use a recognition test to determine if viewers remember the ad, or a market test to evaluate changes in sales and traffic after the ad aired.
Step-by-step explanation:
To measure the effectiveness of the television commercial it recently ran, The Bedford Bagel Shop would most likely use a recognition test or a market test. A recognition test involves showing the commercial to a group of individuals who may have seen it on TV and then asking them if they recognize it, which could help The Bedford Bagel Shop understand if the commercial is memorable to viewers. Alternatively, a market test entails evaluating sales figures and customer traffic before and after the commercial aired to determine if there was a noticeable impact on business performance. On the other hand, recall tests, which require individuals to retrieve information without cues, or portfolio tests, which evaluate a body of ads together, are less directly related to the effectiveness measurement of a single commercial.
