Does statistical correlation r have units?
No, r is a coefficient.
Two variables are said to display correlation if?
cause n affect
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,
What is the correlation between tablet hardness unit SCU and Kp?
1 kp=1.4 S.C.U. (Strong-Cobb Units)
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
Does statistical correlation r have units?
No, r is a coefficient.
Is the correlation coefficient a pure number without units?
Yes.
When the units of measurement are changed what happens to the correlation of the data?
My understanding is, nothing changes. The correlation will be the same regardless of what units are used. Others may have a deeper level of understanding and suggest something else.

How do ATMS affect people who have their money stored in banks?
Almost no correlation...

correlation between rock units is impossible

What are three types of correlation in maths?
In mathematics, the three types of correlation are positive correlation, negative correlation, and zero correlation. Positive correlation occurs when two variables move in the same direction, meaning that as one increases, the other also increases. Negative correlation happens when one variable increases while the other decreases. Zero correlation indicates no relationship between the two variables, meaning changes in one do not affect the other.
Does Lamictal affect serum HCG results?
No. There is no known correlation between the two.
What is the correlation coefficient of -0.80 is found between factor A and factor B?
The correlation coefficient is a statistical measure of the extent to which two variables change. A correlation coefficient of -0.80 indicated that, on average, an increase of 1 unit in variable X is accompanied by a decrease of 0.8 units in variable Y. Note that correlation does not imply causation.
Does t5 affect the contraception pill?
No there is no correlation to T5 and oral BCP. But it does effect your thyroid.
What can you say about the relationship between a correlation r and the slope b of the least squares line form of data?
You can say that the correlation is positive if and only if the slope is positive. The correlation is zero if and only if the slope is zero. And the correlation is negative if and only if the slope is negative. On the other hand, slope does change when your measurement units change, while correlation does not change. (For example, the correlation between height in inches and weight in pounds will be the same as the correlation between height in centimeters and weight in kilograms, as long as both sets of measurements were taken on the same observations.)
