WebThe distinction between interval and ratio scales is rather subtle: a ratio scale has a true zero point, whereas the interval scale does not. If there is a zero value on an interval scale, it is merely an arbitrary point on the scale that is regarded as "zero" by definition. The classic illustration of interval and ratio scales is temperature. WebAmong these, 175 (51.8%) did not know the recommended daily salt intake.
