Kinds of Variables:
1.               Discrete variable 2.               Continuous variable	3.               Quantitative variable 4.               Quantitative variable
1.               Discrete variable	2.               Continuous variable
Definition1: A variable that can assumed only specified values between a set of a values that is the values are taken by jumps, is called discrete variables. Definition2: A discrete variable takes on values which are integers or whole numbers” Examples: 1.    Number of pages in a book. 2.    Number of rooms in a house. 3.    Price 4.    Income 5.    Saving 6.    Consumption 7.   Number of children in family can be 0,1,2… but cannot be 2.5 or 3.84	Definition: “A variable that can assume any value either fractional or integral between two specified limits is called continuous variables”. Examples: 1.         Heights and weights are students. 2.         Speed of a car or jumps. 3.         Temperature. 4.         Rain fall. 5.         Weight of a person. 6.         Height of a plant.
Quantitative variable	Qualitative variable
Definition: “A characteristics whose change is expressed numerically is called quantitative variable” Examples: Heights, weights, age , income etc.	Definition: “A non-numerical characteristic which vary in quality is called qualitative variable or attribute”. The data determined from a qualitative variable are called qualitative data. Examples: Education, poverty, sex, beauty
