Answer:

3. Intact groups

Explanation:

In this design, intact groups are groups of individuals that are already formed, so the researcher has no guarantee of their initial equivalence. The problem is that if the initial equivalence of the groups is not guaranteed, it can be questioned that the differences between the groups after the intervention are due to the effect of the experiment.

dedylja [7]

In the <u>trial</u> stage of the adoption process, the consumer may buy the product to experiment with it in use.

Explanation:

There are basically 5 different stages in the consumer adoption process.

1. Awareness: This first stage is concerned with the consumer being exposed to an innovation or product. Right now he does not have too much information about it, and may not even pay too much attention to it.

2. Interest and Information: It is at this second stage that the consumer wants to voluntarily know more about the said product. He starts collecting information about it from various sources.

3. Evaluation: In this third stage, once the consumer has accumulated all the information he can by means of various sources, he starts comparing the features and qualities of the new product with other already existing products.

4. Trial: After the first three stages, now the consumer is ready to try out the product for the first time. He may go ahead and purchase it, or if free samples are readily available, he may use those too.

5. Adoption: The fifth and last stage of the consumer adoption process is about the consumer purchasing the said product, after all the trials and evaluations.
