Nominal scales represent categories and can be counted

Nominal scales represent how often an event occurs

Nominal scales generally tell us descriptive information about what happened, when it happened, and how many times it happened

. In comparing ordinal scales to nominal scales, which is true?

Ordinal and nominal scales are both quantitative, but ordinal scales allow addition and subtraction.

Ordinal scales tell us what category a datum falls into but nominal scales tell us about frequency of events.

Ordinal scales have rank order whereas nominal scales do not.

. Which of the following is on an ordinal scale but not interval or ratio scale?

. Which of the following is false about ordinal scales?

they are qualitative data

they do not have a true 0 point

the distance between any two ranks are equal

. Which of the following is true about ordinal scales?

Zero on an ordinal scale represents an absence of measurement.

The distance between any two ranks can differ from two other ranks.

The data have equal intervals between every rank.

You can calculate averages that are meaningful.

. Identify one important characteristic that interval and ratio scales share that is not like that of ordinal and nominal scales.

Unlike nominal and ordinal scales, you cannot calculate means for ratio and interval scales.

Interval and ratio scales are qualitative, whereas nominal and ordinal scales are quantitative.

Ratio and interval scales have equal numerical distances between any two adjacent scale points, but nominal and ordinal scales do not.

Ratio and interval scales are used for descriptive statistics only whereas nominal and ordinal scales are not.

. Interval and Ratio scales both lead to obtaining what type of data?

Quantitative

Qualitative

Descriptive

Inferential

Ordinal scales are quantitative and interval scales are not.

Interval scales have more than one number representing the same measurement, but ordinal scales do not.

Ordinal scales do not have equal intervals between adjacent scale points but interval scales do.
