5. __ scales entail the comparison of different objects. For instance key informants may be asked to indicate if they prefer Coca Cola or Pepsi. Nominal Stapel Semantic differential Comparative Likert

The answer is **Comparative**. <br /><br />Here's why:<br /><br />* **Comparative scales** directly compare two or more objects or concepts. This is exactly what the example describes: asking informants to choose between Coca-Cola and Pepsi.<br /><br />Let's look at why the other options are incorrect:<br /><br />* **Nominal scales:** These scales categorize data into distinct groups without any inherent order or ranking. <br />* **Stapel scales:** These scales measure the intensity of a single concept or attribute, often using a single adjective.<br />* **Semantic differential scales:** These scales use bipolar adjectives (e.g., good/bad, strong/weak) to measure attitudes or perceptions.<br />* **Likert scales:** These scales use a series of statements with a range of responses (e.g., strongly agree, agree, neutral, disagree, strongly disagree) to measure attitudes or opinions. <br /><br />**In summary:** Comparative scales are specifically designed for comparing objects, making them the most appropriate choice for the given example. <br />
