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
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.
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
What is a Correlation coefficient of 0.00457?
Evidence that there is no correlation.
What are the trends of a line?
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
Properties of correlation cofficient?
why correlation cofficient always lies between 1 and -1
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. .

What has the author Eugene Buth written?
Eugene Buth has written: 'Correlation of concrete properties with tests for clay content of aggregate'
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?

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.
Auto correlation and cross correlation?
Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
What are three types of correlations?
positive correlation-negative correlation and no correlation
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
What is the maximum and minimum value of the correlation coefficient?
The correlation can be anything between +1 (strong positive correlation), passing through zero (no correlation), to -1 (strong negative correlation).
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
