Algebraic Expression Definition
An algebraic expression is a mathematical statement composed of variables and constants that is typically algebraic in form. Algebraic expressions are used to represent mathematical problems and equations. Variables in Algebra – Definition Types and FAQs.
What is Meant by Variable?
A variable is a letter, number, or symbol that stands for a quantity that may change. For example, in the equation y = 2x + 1, the letter y stands for the variable quantity that may change as x changes. In other words, y is a function of x
1. Dependent Variable
The dependent variable is the variable that is being studied and is thought to be affected by the independent variable. In most experiments, the dependent variable is the variable that is being measured to determine the results of the experiment.
2. Independent Variable:
The independent variable is the variable that is being manipulated by the researcher in an experiment. The independent variable is the variable that is thought to cause a change in the dependent variable.
2. Independent Variable
The independent variable is the variable that is manipulated by the researcher. In an experiment, the independent variable is the variable that is changed by the researcher in order to see its effect on the dependent variable.
3. Quantitative Variable
A quantitative variable is a measure that can be expressed numerically. It is often a characteristic or attribute of something that can be measured. Examples of quantitative variables include age, weight, height, and income.
4. Categorical Variables
A categorical variable is a variable that can take on only a finite number of values. For example, the gender variable can take on the values male or female. The race variable can take on the values white, black, asian, and hispanic.
5. Quantitative Variables
A quantitative variable is a variable that can take on any number of values. For example, the age variable can take on the values 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100.
