Artificial Variables are used to get an initial basic variable from
the constraints while preparing the initial basic feasible solution table. Constraints of >=
type and = type don't provide any basic variable. So, artificial variable is added
arbitrarily to get the basic variable

What is a definiton of a operational definiton?
An operational definition defines something (e.g. a variable, term, or object) in terms of the specific process or set of validation tests used to determine its presence and quantity. That is, one defines something in terms of the operations that count as measuring it.
What is the operational definition of intelligence?
Police operational intelligence is not a term that is used very often. Police operational intelligence is a term used by undercover officers that collect evidence.
What is a n independent variable?
an independent variable is a figure usually shown as a letter that is used in the scientific theory. An independent variable is used in a hypothesized experiment in which this variable is unchanged and is used to effect the dependent variable somewhere in the experiment.
What is the definition of dependent variable?
A variable in a research design that is free to change over a range of different experimental treatments. You have probably made a hypothesis that the dependent variable will change in some systematic way as the experimental treatments change. Examining the data that you generate will tell you whether or not your hypothesis is right.Term used in regressionanalysis to represent the element or condition that is dependent on values of one ormore other independent variables.Basically a dependent variable is an scientific term mostly used in science projects.Dependent variable means an variable that is changed by the expirment.
What are Explanatory variable?
Explanatory (or predictor) variable: A variable which is used in a relationship to explain or to predict changes in the values of another variable; the latter called the dependent variable.
What is a operational variable?
An operational variable is a variable that is defined and measured in a specific and observable way so that it can be clearly understood and used in research or study. It helps to ensure that data collected is consistent and allows for accurate comparisons and analysis.
An operational definition is sociology?
In sociology, an operational definition refers to a specific way of measuring a concept or variable so that researchers can observe and quantify it in a study. This definition outlines the procedures and criteria used to identify and evaluate the concept under investigation, helping to ensure consistency and replicability in research findings.
Operational variable in science?
Operational variables in science are measurable factors that are directly manipulated or controlled by the experimenter in order to study their influence on a particular phenomenon. These variables are defined specifically in terms of how they will be measured or manipulated in an experiment to ensure consistency and objectivity in the research process. By operationalizing variables, researchers can effectively test hypotheses and draw reliable conclusions based on empirical evidence.
What is the role of computer in operational research?
Operational research is the discipline where advanced analytical skills are applied for better decision making. Computers are widely used in many cases to prove the correctness of the decision. Below are some links that will give more information.
What are the characteristics of research objectives?
1.It's phrased in good operational words such as "to describe" "to compare" etc, (bad operational terms such as "to understand", "to appreciate", and "to study" should not be used.) 2.It should clearly indicate, - the purpose of doing - where will it be done - who are the subjects - what will be done in the research. In brief it summarize what is to be achieved by the research.
Define operational definition as distinct from lexical definition?
Operational can be defined as the process of operationalization that is used to define a variable or an object in terms of a process that is needed to determine its quantity, duration, and existence. An operational definition can, when operationalized to a greater degree, besides the procedure needed to bring something into existence.
Which type of research method is used to show cause and effect that one variable causes change in another variable?
The experimental research method is typically used to show cause and effect between variables, where one variable is manipulated to observe the effect on another variable. This method involves randomly assigning participants to different conditions and controlling for extraneous variables to establish a causal relationship.
What is a definiton of a operational definiton?
An operational definition defines something (e.g. a variable, term, or object) in terms of the specific process or set of validation tests used to determine its presence and quantity. That is, one defines something in terms of the operations that count as measuring it.
Who invented artificial hockey turfs?
Artificial turf was first invented in the early 1960s by an RTP research team headed by David Chaney. It was first used for field hockey in the 1970s.
Which research method is used to set up a cause-effect relationship between two or more variables?
Experimental research method is often used to establish a cause-effect relationship between variables. This method involves manipulating one variable (independent variable) to observe the effect it has on another variable (dependent variable), while controlling for other potential influencing factors. Random assignment to different groups and proper control are key aspects of experimental research.
The ENIAC computer was used for what purpose?
ElectronicNumericalIntegratorAndComputer [ ENIAC ], the first operational electronic digital computer was used to compute artillery firing tables for the U.S. Army's Ballistic Research Laboratory.
What are the roles of variables in the qualitative design?
Variables in qualitative research help to capture and analyze different aspects of the research phenomenon. They guide the researcher in exploring relationships, patterns, and themes within the data. Variables can also be used to categorize and compare different attributes or characteristics of the participants in the study.
