You can use the mode as a measure of central tendency for what scales?

• A. Nominal only
• B. Ratio and Interval
• C. All scales
• D. Ordinal only

Answer: (C)

Mode identifies the value that occurs most often. Because this relies on frequency counts rather than any arithmetic properties of the scale, it can be used with any data scale: nominal, ordinal, interval, or ratio. For nominal data, you pick the most frequent category (the category that appears the most). For ordinal data, you do the same with the ordered categories. For interval and ratio data, you count how often each numeric value appears and take the most common value. With continuous data, there can be one or more modes if several values tie for the highest frequency, but the idea remains the same. Hence, mode works across all scales.
