Does correlation always equal causation?
No! Correlation by itself is not sufficient to infer or prove causation.
If there is no correlation r is equal to?
0, within statistical error.
What plus and minus signs mean in correlation mean?
They equal a minus and two +'s or two -'s equal a + :)
What is the name for when 3 lines cross with coordinates?
positive 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.
What is the correlation if x values are equal to the y values?
Positive Correlation
What type of correlation do you have when are is equal to one?
A correlation coefficient of 1 (r=1) is a perfect positive correlation.

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).
