There are two types of variations which include continuous variations and discontinuous variations. Continuous variations are those which are quantitative and include the smooth grading between two extremes. The first example of continuous variations includes, heights in human population. These variations can be measured on a quantum and not in discrete units. For example, heights of people can be as 5.1, 5.4, 6.1 etc. They are not discrete values. Another example can be the temperature values. The value of temperature can be 12.1 Co, 37.9 Co, 67.0 Fo. Therefore temperature scale is another example of continuous variations.
