Temperature measurement recorded in Fahrenheit is quantitative in nature that is, it deals with quantity or numbers and not with category or level which is reffered to as qualitative. The measurement levels or scale avaliable for recording quantitative variable are the ratio and interval scale. However, difference between both scales lies in the existence of true zero in the measurement. In the ratio scale, True zero exists. However, in the interval scale, there is no true zero.
