Final answer:
An officer's rank in the military is measured at the ordinal level because ranks exhibit a clear hierarchy, but intervals between them are not equal and no true zero exists.
Step-by-step explanation:
The variable 'an officer's rank in the military' can be measured on an ordinal scale. This is because military ranks imply a hierarchy where each rank is clearly ordered relative to others, but the intervals between the ranks are not necessarily equal, and there is no true zero point. Thus, the ranks can be ordered, but differences between the ranks are not measures of equal increments.
The level of measurement for an officer's rank in the military is ordinal.
An ordinal scale data can be ordered, but the differences between the ranks cannot be measured. For example, we can rank officers from highest to lowest, such as General, Colonel, Lieutenant, but we cannot determine the exact difference in rank between a General and a Colonel.
