Detailed explanation-1: -For example, temperature in Celsius or Fahrenheit is at an interval scale because zero is not the lowest possible temperature. In the Kelvin scale, a ratio scale, zero represents a total lack of thermal energy.
Detailed explanation-2: -Most experts recommend that the ideal temperature setting for a refrigerator is between 35-38°F (1.6-3.3°C).
Detailed explanation-3: -An interval variable is a one where the difference between two values is meaningful. The difference between a temperature of 100 degrees and 90 degrees is the same difference as between 90 degrees and 80 degrees.
Detailed explanation-4: -Keep your appliances at the proper temperatures. Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C).
