Correlation is a way of testing whether there is a linear relationship between two variables of their transformed versions. If there is no correlation then all that it means is that there is no linear relationship between the two or between their transformed versions. It certainly does not mean that there is no relationship. For example, if y = a*x^2 + b where a and b are constants then, because of symmetry, the correlation between x and y is 0.

What does variables mean in a science project?
That means something that will change, basically, the point of your experiment
How you manipulate variables?
'Manipulating variables' means to change some of the portions of a specific formula that are open to change, and hence variable. Take: ( x + y ) = 5 You may discretionally change the variables x and y to anything from minus infinity to five and the equation will still be solvable. To do so would be to manipulate those variables.
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.

What does constant variables means?
Constant means strait line and variable is an arch which is not a strait line
Is Statistically independent random variables are uncorrelated and vice versa?
the statistically independent random variables are uncorrelated but the converse is not true ,i want a counter example,
Why principal component analysis is implemented in face recognition?
to convert raw data of correlated variables to data matrix of uncorrelated variables (Principal Component)
What is conditional expectation of 2 uncorrelated random variables-is it equal to unconditional expectation?
Yes. the conditional expectation of X given Y is simply the expectation of X if X and Y are uncorrelated. This is a consequence of one of the properties of conditional expectation.
Correlated and uncorrelated noise?
If I have two source of noise let as say two laser diodes so the pink noise that generate fro both of them is it correlated or uncorrelated
Will the variance of the difference of two independent normally distributed random variables be equal to the SUM of the variances of the two distributions?
Yes it is. That is actually true for all random vars, assuming the covariance of the two random vars is zero (they are uncorrelated).
What is the solution of the system means in math?
It means that values are assigned to each of the variables in such a way that, when replacing the variables for those values, EACH of the equations will be true.
What is the implication of any correlation found between the variables?
Correlation is a measure of the degree to which two variables change together. Positive correlation means that the variables increase together and decrease together. Negative correlation means that one variable increases when the other decreases.Correlation does not imply causality.Correlation is a measure of the degree to which two variables change together.

What means controlling variables?
what does controlling the variable mean?
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 does maipulated variables mean?
To manipulate a variable means to change it.
What is x x?
xx is means kisses in a simpler form! Or... it means two unknown variables.
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
