as the covariance of the two random variables (X and Y) is used for calculating the correlation coeffitient of those variables it indicates that the relation between those (X and Y) is positive, so they are positively correlated.

Can probability values be negative?
No. Probability values always have to be positive.
How do you find the quadrant number of a point?
If the points have both positive y-values and x-values it is quadrant 1 If the points have a negative x-value and a positive y-value it is quadrant 2 If the points have both negative y-values and x-values it is quadrant 3 If the points have a positive x-values and a negative y-value it is quadrant 4
Are electron affinity values usually positive or negative numbers?
Positive for nonmetals and negative for metals
Positive and negative implications of the value orientations of Filipinos on national development goals?
Filipino people have positive and negative aspects of their values. It is important to recognize the positive aspects of these values in order for them achieve their national development goals.
Which is the first quadrant in a coordinate grid?
The top right one... it is the first because it is where both the x-value and y-values are positive. The second quadrant is the top left. The x-values are negative and the y-values are postive. The third quadrant is the bottom left. The x-values are negative and the y-values are negative. The fourth quadrant is the bottom right. The x-values are positive and the y-values are negative.
How do you find covariance of two variables?
The covariance between two variables is simply the average product of the values of two variables that have been expressed as deviations from their respective means. ------------------------------------------------------------------------------------------------- A worked example may be referenced at: http://math.info/Statistics/Covariance
What is the difference between correlation and covariance?
Correlation is scaled to be between -1 and +1 depending on whether there is positive or negative correlation, and is dimensionless. The covariance however, ranges from zero, in the case of two independent variables, to Var(X), in the case where the two sets of data are equal. The units of COV(X,Y) are the units of X times the units of Y. correlation is the expected value of two random variables (E[XY]),whereas covariance is expected value of variations of two random variable from their expected values,

Can probability values be negative?
No. Probability values always have to be positive.
How 2 calculate a variance-covariance matrix?
See related link. You can use Excel, if you dataset is not too big. Generally, if I have a table of data, with n columns corresponding to n variables with N observations, I can calculate the covariance of columns a and b, using excel covar function, covar(range of first data values, range of second data values) To keep things organized, you may want to name the ranges of your columns and use them as the arguments in the covar.
