question 1\n2 pts\na researcher records the time (in seconds) it takes for participants to complete a task. what type of variable is this?\nnominal\nordinal\ninterval\nratio

Answer

Brief Explanations:

To determine the variable type:

  • Nominal: Categorical, no order (e.g., colors). Time is not nominal.
  • Ordinal: Ordered categories (e.g., rankings), but time has continuous numerical values.
  • Interval: Numerical, but no true zero (e.g., temperature in °C). Time has a true zero (0 seconds means no time elapsed).
  • Ratio: Numerical with a true zero and equal intervals. Time (in seconds) has a true zero (0 seconds is meaningful) and consistent intervals (1 second is the same duration everywhere). Thus, task completion time is a ratio variable.

Answer:

D. Ratio
