Question

identify the level of measurement corresponding to the data \salespersons performance: below average, average, above average\ associated with robotics.
○ interval
○ ordinal
○ none of these choices
○ nominal
○ ratio

Explanation:

1. Recall the levels of measurement:

• Nominal: Categories with no order (e.g., colors).
• Ordinal: Categories with a natural order (e.g., rankings like below average, average, above average).
• Interval: Ordered with equal intervals, no true zero (e.g., temperature in °C).
• Ratio: Ordered with equal intervals and a true zero (e.g., height).

1. The data "below average, average, above average" has a clear order (ranking of performance) but no equal intervals or true zero. So it fits ordinal level.

Answer:

B. ordinal
