Continuous (Interval or Ratio) Scale Data


 Data points where there is a sense of order and rank. In addition, the magnitude of difference between each number is the same and measurable.
 Made up of two types of scales of data, interval scale and ratio scale.
 The only difference between interval and ration scale data is whether or not the scale being referred to has an absolute zero.
 Interval scale data:
 When numbers have units that are of equal magnitude as well as rank order on a scale without an absolute zero
 Scales of this type can have an arbitrarily assigned "zero", but it will not correspond to an absence of the measured variable. For example, temperature in Fahrenheit scale.
 Ratio scale data:
 When numbers
have units that are of equal magnitude as well as rank order on a scale with an absolute zero
 Examples include: heart rate, blood pressure, distance.
 For interval and ratio data can be converted into ordinal data, but ordinal data cannot be converted into continuous data.
 Can be described as a mean or median.
