Something that can be changed in an experiment.
CONTROLLED VARIABLE = something you want to keep the same throughout the experiment. Usually temperature, time of incubation, concentration of the reagents, etc are controlled because if they were to change, it would change the results you get. Thus, without controlled variables, any differences you see in your data may not be due to what it is you were wanting to see. For example, if you were looking at the effect of temperature on how fast water evaporates, then the volume of water you use should be the same in each repetition.
INDEPENDENT VARIABLE = something you want to change, to see if it makes a difference to your results. By changing this, you want to see if it causes a change in results. For example, in the above example, the independent variable would be the temperature - you want to see if an increase in temperature makes the water evaporate faster.
DEPENDENT VARIABLE = what you are actually looking at. In the example given, the dependent variable would be how fast the water evaporates. You don't change this directly, but you are changing the temperature, which in turn changes this.
variables are nothing but a space provided to store values.It is a name for a memory address.system recognises it by memory address and we,as their names....the name of a variable cant be a keyword i.e. words already defined for specific purpose(they carry their own meaning) like int,if,etc..

What does Correlation of plus 1.00 mean?
It mean that there is no correlation between the two variables. The variables are the same.
What dose Variables mean?
Variables mean whose values are not constant, such as x, y , z this is in algebra
If coefficient of correlation r between two variables is zero does it mean that there is no relationship between the variables Justify your answer?
"If coefficient of correlation, "r" between two variables is zero, does it mean that there is no relationship between the variables? Justify your answer".
What is the standardizing variables?
There doesn't exist such a thing. What does exist are standardized variables, which are variables with mean = 0 and standard deviation = 1
What does a b and c mean in math?
A,b,c are variables. They usually refer to the sides of a triangle, but also can mean just normal variables.

What are variables and independent variables?
those words either mean math or science words
What does a b and c mean in math?
A,b,c are variables. They usually refer to the sides of a triangle, but also can mean just normal variables.
What means controlling variables?
what does controlling the variable mean?
What do you mean by variables exponent in the degree of term?
i am not sure
How do you get the mean in math?
you add all the numbers together then divide the answer by the number of numbers there are
What does correlation mean in maths?
Correlation is a statistical measure of the linear association between two variables. It is important to remember that correlation does not mean causation and also that the absence of correlation does not mean the two variables are unrelated.
What does it mean when 2 variables have a relationship?
Usually it means that each of the variables is dependent on the other. if one changes, so does the other.
What do you mean by implicit and explicit variables declaration in visual basic?
implicit means you must declare variables before using them while explicit is not a must you declare variables before using them
