Paper 3 · June 2023 · Statistics: measurement scales, Poisson, chi-square, spatial autocorrelation

Classify the data '20 degrees C, 23 degrees C, 32 degrees C' into the appropriate measurement scale.

Model answer

interval

Also accepted: interval scale, interval data

Explanation

Temperature in degrees Celsius has equal intervals but an arbitrary zero, so differences are meaningful while ratios are not: 32 degrees is not twice as hot as 16 degrees. That is the interval scale.
