Interval scales have measurements which are an equal distance from each other. For example, the difference between a temperature of 70 degrees and 80 degrees is 10, which is the same as the difference between 40 degrees and 50 degrees.
Ratio scales are similar to interval scales but include an absolute 0 measurement, which signifies the point when the characteristic being measured vanishes. What this also means is that 3 feet is 3/2 times as far as 2 feet. The ratio of the values is maintained. This latter quality is not maintained in the temperature scales in common use: 5 deg C is not half as warm as 10 deg C (or degrees Fahrenheit, for that matter). THat only works with the absolute temperature scale = Kelvin.

What are the difference between successive values on a scale?
The difference between the successive values on a scale is an interval.
What is the difference between the interval scale and the ratio scale?
Interval scales have measurements which are in equal distance from each other. For example, the difference between 70 degrees and 80 degrees is 10, which is the same as the difference between 40 degrees and 50 degrees. Ratio scales are similar to interval scales but include an absolute 0 measurement, which signifies the point when the characteristic being measured vanishes. For example, income (measured in dollars) at 0 means no income at all. Basically, interval and ratio scales are the same, but ratio scales must be able to be measured at a zero starting point.
