the following appear on a physicians intake form. identify the level of measurement of the data. (a) temperature (b) time since last visit (c) happiness level (scale of 0 to 10) (d) marital status (a) what is the level of measurement for \temperature\? interval ordinal ratio nominal (b) what is the level of measurement for \time since last visit\? ordinal nominal interval ratio

Answer

Brief Explanations:

  • (a) Temperature has a meaningful order and equal - sized intervals between values, but 0 is an arbitrary zero (e.g., 0°C does not mean the absence of temperature), so it is interval.
  • (b) Time since last visit has a true zero (0 time means no time has passed since the last visit) and ratios are meaningful (e.g., twice as long since the last visit), so it is ratio.
  • (c) Happiness level on a scale of 0 - 10 has an order (higher numbers mean more happiness), so it is ordinal.
  • (d) Marital status (e.g., single, married, divorced) is a category with no order or numerical value, so it is nominal.

Answer:

(a) Interval (b) Ratio (c) Ordinal (d) Nominal
