Question

A dataset records classroom temperatures in Fahrenheit. The analyst converts them to Kelvin before applying a multiplicative model that assumes ratios of temperatures are meaningful. Critically evaluate whether this modeling assumption is justified.

Accepted Answer

Justified — Kelvin has an absolute zero, so after conversion the data are ratio-level and multiplicative models comparing relative temperature magnitudes are physically meaningful.

Answer

Justified only when the analyst normalizes Kelvin values to a 0–1 scale first; otherwise ratio interpretations are valid but computational algorithms will diverge without normalization.

Answer

Not justified — converting to Kelvin actually makes temperatures nominal because thermodynamic concepts become irrelevant when modeling classroom comfort, so multiplicative comparisons are invalid.

Answer

Not justified — Fahrenheit and Kelvin are both interval-level and conversion does not add an interpretable zero, therefore ratios remain meaningless and multiplicative models fail.
