Question

classify each variable by their level/scale of measurement. a ski resort records the daily temperatures during the month of january. a nominal b c interval d ordinal

Explanation:

1. Recall the definitions of each scale:

• Nominal: Categorical, no order (e.g., colors).
• Ordinal: Categorical with order (e.g., ranks).
• Interval: Numerical, equal intervals, no true zero (e.g., temperature in °C/°F, where 0 doesn’t mean no temperature).
• Ratio: Numerical, equal intervals, true zero (e.g., height, weight).

1. Daily temperatures (e.g., in °C or °F) have equal intervals (the difference between 10°C and 20°C is the same as 20°C and 30°C) but no true zero (0°C doesn’t mean no temperature exists). So it’s Interval. Wait, but if using Kelvin, it’s Ratio, but the problem likely refers to °C/°F. However, the options include Interval (C) and Ratio (B, though B’s text is cut off, assuming Ratio was misselected). Wait, the correct scale for temperature (non - Kelvin) is Interval. But let's re - evaluate:

• The variable is daily temperatures. Temperature in Celsius or Fahrenheit:
• Nominal: No, it's numerical.
• Ordinal: No, it's not just ordered categories, it's numerical with equal intervals.
• Interval: Yes, because there's no true zero (0°C doesn't mean absence of temperature), and equal intervals.
• Ratio: No, because of no true zero.
• But the original selection was B (Ratio, maybe a typo, but assuming the correct answer is C. Interval. Wait, maybe the problem has a typo, but based on standard measurement scales:
• Temperature (°C/°F) is Interval. So the correct option is C. Interval.

Answer:

C. Interval
