Numerical rating scales are tools used to quantify subjective opinions or experiences. They typically consist of a range of numbers, often from 1 to 5 or 1 to 10, where each number corresponds to a specific level of satisfaction, agreement, or quality. For example, in a customer satisfaction survey, a rating of 1 might indicate "very dissatisfied," while a rating of 5 could mean "very satisfied." These scales are commonly used in various fields, including psychology, market research, and healthcare. They help researchers and organizations gather consistent data, making it easier to analyze trends and make informed decisions based on the feedback received.
