What are the properties of correlation coefficient?
The correlation coefficient is symmetrical with respect to X and Y i.e.The correlation coefficient is the geometric mean of the two regression coefficients. or .The correlation coefficient lies between -1 and 1. i.e. .
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
Properties of regression coefficient-statistics?
8.7.4 Properties of Regression Coefficients:(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity.(c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, providedr > 0.(d) Regression coefficients are independent of the changes of origin but not of scale.
Are negative correlation and reverse correlation same?
No.
Does the units affect the correlation?
No. The units of the two variables in a correlation will not change the value of the correlation coefficient.

What is the 5 in 5n called?
That 5 is the cofficient of the term. The "n" is the variable!
What is the difference between causation and correlation?
Correlation is when two things are related or have similar properties. They can exist independently. Causation means that one thing made the other thing happen
What is the difference between hall-effect in metals and semiconductor?
because we have hall cofficient =1/ne. where the n=no of electron ,e=charge of electron. we know that "n "in metal is very large. so that R=HALL COFFICIENT" is very small FOR it .so we can not find sufficient result for hall cofficient so we use semi conductor which gives non zero hall cofficient.
What is Cofficient of restitution of a perfectly plastic impact?

What is cofficient in term 5x?

What has the author W Matthes written?
W. Matthes has written: 'Measurement of correlation properties of the bubble fiel in two-phase flow'
How do correlation and causation differ?
Correlation is when two things are related or have similar properties and they can exist independently. Causation means that one thing made the other thing happen.
