Final answer:
The question given is a scalar question, which is intended to gather quantitative data through a rating scale, commonly used in surveys to measure subjective experiences in a structured way. The correct answer is B.
Step-by-step explanation:
The question "On a range of 1 to 10, how would you rate the service in this restaurant?" is an example of a B. Scalar question. Scalar questions, often associated with survey or questionnaire design in research methodologies, ask for a rating or a ranking on a scale, typically to gather quantitative data regarding opinions, perceptions, or attitudes. These scales are common in customer satisfaction surveys or product reviews, enabling researchers to quantify subjective experiences in a structured manner. Scalar questions fall under the broader category of quantitative research, which deals with numbers and values that can be measured and compared.
In the context of data types, quantitative data can be further broken down into continuous or discrete. Examples of quantitative discrete data include the number of pairs of shoes you own, the number of classes you take per school year, or the number of correct answers on a quiz. These are countable numbers. On the other hand, quantitative continuous data represent measurements that can be infinitely divided such as the distance from your home to the nearest grocery store, weights of sumo wrestlers, or IQ scores.
Qualitative data, in contrast, are non-numeric and descriptive, such as the type of car you drive or the type of calculator you use. This type of data often comes from open-ended questions, which are used to collect detailed written responses that reveal deeper insights into a person's thoughts, beliefs, or feelings. Collecting both qualitative and quantitative data leads to a comprehensive understanding of the research subject.
