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.
Q. How do you define variables in research?
Variable Definition in Research A variable is any property, a characteristic, a number, or a quantity that increases or decreases over time or can take on different values (as opposed to constants, such as n, that do not vary) in different situations. When conducting research, experiments often manipulate variables.

Q. How do you define a variable in a word problem?
Explanation: A general approach is to let the variable be whatever the question asks you to find…… or the price of pears and peaches, then….. Let the variable be the smaller number and then write an expression for the other value.
Q. How do you define a variable in algebra?
Algebra – Basic Definitions A Variable is a symbol for a number we don’t know yet. It is usually a letter like x or y. A number on its own is called a Constant. A Coefficient is a number used to multiply a variable (4x means 4 times x, so 4 is a coefficient)
Q. Why are variables important in algebra?
In addition to numbers, variables are commonly used to represent vectors, matrices and functions. Making algebraic computations with variables as if they were explicit numbers allows one to solve a range of problems in a single computation.
Q. Why is it important to know the different types of variables in research?
Dependent and independent variables are also important because they determine the cause and effects in research. It can be concluded that the paper has shown the different types of variables, the relationship between dependent and independent variables and their importance in research.
Q. What are the different kinds of variables in quantitative research?
They are variables (concepts that can vary). Quantitative research involves many kinds of variables….There are four main types:
- Independent variables (IV).
- Dependent variables (DV).
- Sample variables.
- Extraneous variables.
Q. What is variable in psychology?
A variable is something that can be changed or varied, such as a characteristic or value. Variables are generally used in psychology experiments to determine if changes to one thing result in changes to another. Variables play a critical role in the psychological research process.
Q. Is gender a variable?
Most often, gender is represented by a dichotomous variable with the possible responses of woman/man or female/male, although gender is not a binary variable. It is, however, rarely defined what is meant by gender.
Q. What kind of variable is size?
Ordinal variables have an inherent order. For example: Likert scales (strongly disagree, disagree, neutral, agree, strongly agree) t-shirt size (small, medium, large)
Q. What kind of variable is attitude?
In the above examples, sex is an example of a nominal scale of measurement, or a classification or categorization; attitude is ordinal, or an ordering or ranking of responses; and age has an interval and ratio scale of measurement, with meaningful measures of distances and ratios between values.
Q. What type of variable is birth order?
Birth Order as Independent Variable .
