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).
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.
In an efficient market the correlation cofficient between stock returns for two non overlapping time periods should be?
In an efficient market, the correlation coefficient between stock returns for two non-overlapping time periods should be close to zero. This reflects the idea that past stock returns do not predict future returns, as all available information is already reflected in current prices. Consequently, any patterns or trends observed in one period should not persist into another. Thus, the returns are expected to be independent across different time periods.
Which one of the following method serve to measure correlation bw two variable?
cofficient of rank correlation
What are the properties of correlation?
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. .
What is the 5 in 5n called?
That 5 is the cofficient of the term. The "n" is the variable!
What are the properties of correlation coefficient?

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 cofficient in term 5x?
5x 5 is the coefficient and x is the variable.
What has the author Eugene Buth written?
Eugene Buth has written: 'Correlation of concrete properties with tests for clay content of aggregate'
What is the co efficient for window grill painting?
cofficient of window 1mx1m
Does the cofficient of linear expansion depend on length?
No, it is a fundamental mechanical property of the material
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.
Is there a direct correlation between amplitude and wavelength?
No, amplitude and wavelength are independent properties of a wave. Amplitude refers to the height of the wave, while wavelength is the distance between two corresponding points on a wave. They do not have a direct correlation, as changing the amplitude does not affect the wavelength, and vice versa.
