Question: What Is Variable Explain?

What is variable explain with example?

In mathematics, a variable is a symbol or letter, such as “x” or “y,” that represents a value.

For example, a variable of the string data type may contain a value of “sample text” while a variable of the integer data type may contain a value of “11”..

What type of variable is age?

The variable age remains a quantitative continuous variable but the variable we are working on (i.e., the number of weeks since birth) is a quantitative discrete variable.

What are the 3 types of variables?

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

How do you define a variable in programming?

In software programming, variables are names used to hold one or more values. Instead of repeating these values in multiple places in your code, the variable holds the results of a calculation, database call, results of a database query, or other value.

What is variable and its types?

Variables represents the measurable traits that can change over the course of a scientific experiment. In all there are six basic variable types: dependent, independent, intervening, moderator, controlled and extraneous variables.

What are the 5 variables?

There are six common variable types:DEPENDENT VARIABLES.INDEPENDENT VARIABLES.INTERVENING VARIABLES.MODERATOR VARIABLES.CONTROL VARIABLES.EXTRANEOUS VARIABLES.

What are types of variables?

The three types of categorical variables—binary, nominal, and ordinal—are explained further below. A simple version of a categorical variable is called a binary variable. This type of variable lists two distinct, mutually exclusive choices. True-or-false and yes-or-no questions are examples of binary variables.

How do you identify a variable in research?

A variable in research simply refers to a person, place, thing, or phenomenon that you are trying to measure in some way. The best way to understand the difference between a dependent and independent variable is that the meaning of each is implied by what the words tell us about the variable you are using.

What is the importance of variables in research?

2.4 The importance between dependent and independent variables. The importance of dependent and independent variables is that they guide the researchers to per sue their studies with maximum curiosity. Dependent and independent variables are important because they drive the research process.

Why do we use variables?

Variables can represent numeric values, characters, character strings, or memory addresses. Variables play an important role in computer programming because they enable programmers to write flexible programs. Rather than entering data directly into a program, a programmer can use variables to represent the data.

How do you explain variables to students?

A variable is something that can be changed. In computer programming we use variables to store information that might change and can be used later in our program. For example, in a game a variable could be the current score of the player; we would add 1 to the variable whenever the player gained a point.

What is variable example?

A symbol for a value we don’t know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the variable. Why “variable” when it may have just one value?

What are the two types of variables?

What are independent and dependent variables? You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect.
