What is variable and example?

In mathematics, a variable is a symbol or letter, such as “x” or “y,” that represents a value. For example, in the equation below, y is the “dependent variable” because its value is based on the value assigned to the “independent variable” x. …

What type of variable is age?

Mondal[1] suggests that age can be viewed as a discrete variable because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.

What is a quantitative variable?

Quantitative Variables – Variables whose values result from counting or measuring something. Examples: height, weight, time in the 100 yard dash, number of items sold to a shopper. Qualitative Variables – Variables that are not measurement variables. Their values do not result from measuring or counting.
