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.

It is also something that is likely to vary.

What is the differecnce between independent variables and dependent variables?
Every time the independent variables change, the dependent variables change.Dependent variables cannot change if the independent variables didn't change.
What are controlled independent and dependent variables?
control variables: the things that are not changing.Independent variables: the things that you change.Dependent variables: the things that are changed due to the independent variable
Can continuous variables assume a limited number of values between any 2 specific values?
Yes, if you have two limiting variables with other possibles variables between them, the variables between the limiting variables would be continuous.
Can variables be positive or negative?
both, variables can be anything
Why do you use dummy variables?
to quantify the qualitative variables.
What is definning in science?
Science is a particular branch of scientific knowledge.
What are the definning characteristics of matter?
it melt faser in iastic cup Mass, quarks and leptons
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
What is the differecnce between independent variables and dependent variables?
Every time the independent variables change, the dependent variables change.Dependent variables cannot change if the independent variables didn't change.
What are variables that do not change in an experiment?
Variables that do not change in an experiment are independent variables.
The variables that do not change in an experiment are what?
Variables that do not change in an experiment are independent variables.
What are the three variables that play an important role in a Practical Investigation?
Independent Variables, Dependent Variables and Extraneous Variables.
What are explanatory variables in regression?
Explanatory (or independent) variables are variables such that changes in their value are thought to cause changes in the "dependent" variables.
What are stimulus variables?
Stimulus variables are variables that are part of the habitat that an organism reacts to. These variables can be natural parts of the area such as weather.
What are predicting variables?
Variables that you predict.
Anova depends on having independent variables describe an abuse that might occur by having dependent variables?
there are three kinds of variables.a variable must be a situation,condition or a factor1.change or manipulated variables.-are the variables that are being tested or changed.2.constant variables.-are the variables that you are not intended to test or study,or the variables to be kept constant.3.responding variables.-are the results of the maipulated variables.
Are constant variables and derived variables the same?
Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.
