Differentiate between discrete variable and continuous …

Discrete Variable: A discrete variable is one which increases in jumps or in complete numbers. For example, there can't be 2.4 workers in a factory. They can be 1, 2, 3, 4 and so on. Similarly, a factory can't have 4.8 or 2/7 machines. It will be in complete numbers like 1,2,3,4, and soon. Such variable are called discrete variable. Some other examples of discrete variable are number of workers in a factory, number of machines purchased, number of children etc.

Continuous Variable: Those variables which can assume any value in a given range and which increase continuously and not in jumps are called continuous variable. For example, weight of a person can be 45.234kg, it can take any value within a range. No one gains weight in jumps. It increases in continuity. Other examples are height, income etc.Continuos Variable always lies in a particular interval or range .For instance, height of a child is 3.5 metres which lies between 3 and 4.So, here the interval is equal to( 3,4).
