Answer 2

Answer:

In Algebra, a variable is an alphabet which is used to represent the unknown number. It represents the value. A variable is a quantity that may be changed according to the mathematical problem. The generic letters which are used in many algebraic expressions and equations are x, y, z. In other words, a variable is a symbol for a number where the value is not known.

For example, x + 5 = 10

Here “x” is a variable.

The value of the variable “x” can be easily found by solving the equation. In this case, if the equation is solved, the value of the variable “x” is obtained as 5. It means that x = 5.

Similarly, the term variable is used in Statistics also. In Statistics, a variable may be sometimes called a data item. It represents the number/characteristics that can be measured. For example, sex, age, income, capital expenditure are examples of variables in Statistics
