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.

Difference between interval scale and ratio scale?
an ratio scale is where both measurements are in the same unit of measurement and an interval scale is where they are not. i dont know if this helps at all but we are learning about it in maths at the moment and that is the easiest way for me to understand it Beside the features of interval scales, ratio scale carries zero point measurements. Means that the zero value is considered when we do the measurement in ratio scales. Say that it is not only differ between 1 to 10, but there is also different to compare two intervals between 1 to 10, and 100,001 to 100,010 when we measure them (intervals) starting from zero point scales. * * * * * Unfortunately, the first paragraph above is nonsense. An interval scale is one in which the difference between two points can be quantified numerically. However, the zero is arbitrary. The Celsius and scale is an example. The difference between 1 deg C and 3 deg C is twice the difference between 7 deg and 8 deg. But 3 deg C is not 3 times as hot/cold as 1 deg C. A ratio scale is an interval scale with the added requirement of a non-arbitrary zero point such that the value of 3 is three times the value of 1. The Kelvin scale meets those requirements. Scales in common use, that are not interval are the Richter scale (earthquakes) or Beaufort (wind speeds) where the points on the scale are indicators of outcomes.
What type of scale is calendar nominal or ratio or interval?
interval
What is the difference between interval data analysis and ratio data analysis?
Data comes in various sizes and shapes. Two of them are Interval and Ratio. Interval is a measurement where the difference between two values is meaningful and follows a linear scale. For example: in physics, temperature 0.0 on either F or C does not mean 'no temperature'; in biology, a pH of 0.0 does not mean 'no acidity'. Interval data is continuous data where differences are interpretable, ordered, and constant scale, but there is no 'natural' zero. Ratio is the relation in degree or number between two similar things or a relationship between two quantities, ordered, constant scale, with natural zero. Ratio data is interpretable. Ratio data has a natural zero. A good example is birth weight in kg. The distinctions between interval and ratio data are slight. Certain specialized statistics, such as a geometric mean and a coefficient of variation can only be applied to ratio data.
Is year is a ratio scale?
The year is interval scale (no natural zero); your age is ratio.
