Scale measurement refers to the process of quantifying attributes or characteristics using a standardized system. It involves assigning numbers to objects or events based on specific rules, allowing for comparison and analysis. Common types of scale measurement include nominal, ordinal, interval, and ratio scales, each serving different purposes in research and data collection. In practice, scale measurement is essential in fields like psychology, sociology, and market research. It helps researchers gather data on opinions, behaviors, and demographics, enabling them to draw meaningful conclusions. Accurate scale measurement ensures that the data collected is reliable and valid for further analysis.
