Determining a person's reaction time (in milliseconds)would involve measurement on a(n)____ scale of measurement.​
A)​nominal
B)​ordinal
C)​interval
D)​ratio

Quizplus · Accepted Answer

Reaction time is a quantitative variable that can be measured on a ratio scale, as it has a true zero point (i.e. no reaction time is represented by 0 milliseconds) and equal intervals between values. This allows for meaningful mathematical operations such as calculating ratios or differences between reaction times. Nominal, ordinal, and interval scales cannot provide this level of precision.
