Question

Four different thermometers were used to measure the temperature of a sample of pure boiling water. The measurements are recorded in the table below. Thermometer Temperature Reading 1 Temperature Reading 2 Temperature Reading 3 W 100.1°C 99.9°C 96.9°C X 100.4°C 102.3°C 101.4°C Y 90.0°C 95.2°C 98.6°C Z 90.8°C 90.6°C 90.7°C The actual boiling point of pure water is 100.0°C. What can be concluded from the data about the reliability and validity of the thermometers?
