Final answer:
Sampling is the sales promotion technique that typically generates the highest trial rates compared to contests, sweepstakes, and bonus packs. The exercises provided each represent different sampling methods like cluster, systematic, convenience, and simple random sampling, all of which are used in market research.
Step-by-step explanation:
The student has asked which sales promotion technique generates much higher trial rates than advertising and other sales promotion techniques. In this context, sampling, which involves giving a free sample of the product to consumers, is widely recognized to generate a higher trial rate. This is because sampling removes the financial risk for the consumer in trying a new product. On the other hand, techniques such as contests, sweepstakes, and bonus packs, while they can be effective at boosting sales and engagement, may not necessarily result in immediate trial of the product at the same rate as sampling.
For the following four exercises, different types of sampling methods are employed:
- The division of a group into twelve and selecting four random groups is an example of cluster sampling.
- A market researcher polling every tenth person is using systematic sampling.
- Polling the first 50 people who walk into a sporting event represents convenience sampling.
- A computer generating random numbers for selection correlates with simple random sampling.
In the given scenarios, different sampling techniques are utilized to collect data for various research purposes, each method suited to the specific objectives and contexts of the research.
