This means that while no, mathematical operation can be
performed on the readings, it can be performed on the differences between readings. For example, if the difference in temperature between two I objects, A and B, is 15°C and the difference in temperature between two other objects C ' and D, is 45°C, you can say that the difference in temperature between C and D is three II times as great as that between A and B. An attitude towards an issue measured on the Thurstone scale is similar. However, the Likert scale does not measure the absolute intensity of the attitude but simply measures it in relation to another person.
