b. Fahrenheit thermometers
Collects values representing temperatures in Fahrenheit
Collected values representing temperatures in Fahrenheit(F) is an Interval Data. As in the terms of temperature there is fixed interval. As difference between 1F and 3F is same as in 22F and 24F. However, we cannot say that 5F is half than 10F because there is no absolute zero in temperature. Temperature can increase to infinity as well as decrease to infinity in Fahrenheit.

c. Kelvin thermometers Collects values representing temperatures in Kelvin
Collected values representing temperature in kelvin(k) is a Ratio Data. Because in terms of kelvin temperature there is fixed intervals and as well as absolute zero. As there is absolute zero in kelvin temperature we can say that 5 degrees is half hot as compared to 10 degrees.
