Which measurement scale should be used to measure delivery status?

The use of the ordinal measurement scale to evaluate delivery status is appropriate because delivery status typically represents a ranked or ordered set of categories. For instance, delivery statuses can include options such as "Pending," "In Transit," and "Delivered." These categories have a logical order which indicates a progression of the delivery process, where each status conveys information regarding the stage of completion.

In ordinal scales, while the order of the categories is meaningful, the intervals between them are not uniform or measurable. For example, the difference in time it takes for a package to go from "Pending" to "In Transit" may not be the same as the difference from "In Transit" to "Delivered." This characteristic of ordinal scales makes it suitable for capturing the sequential nature of delivery statuses, focusing on ranking rather than exact measurement.

In contrast, other scales like nominal measure distinct categories without any inherent order, ratio scales necessitate an absolute zero and consistent intervals, and interval scales assume equal distances between points on the scale without a true zero point. Thus, these alternatives do not adequately capture the ordered relationship present in delivery statuses, reinforcing why the ordinal scale is the best fit.
