Does correlation always equal causation?
No! Correlation by itself is not sufficient to infer or prove causation.
What type of correlation will the data have for a scatter plot of ages and heights of all students in your school?
It depends on the range of ages, but a moderate positive correlation.
What correlation coefficient best explains the relationship between creativity and intelligence?
both are inter related. an Intellectual always have the creativity and viceversa So the in betwenn the range -1 to +1 ... my heart goes to +1
Is a correlation coefficient of -626 very strong?
A correlation coefficient has a range of -1 to 1. Any number outside of this range has been incorrectly calculated. I note that is you meant to ask - Is r= -0.626 is a very strong correlation coefficient? then the answer No, this value is not a strong indicator that a linear relationship exists. Please see related link. The diagrams showing x-y graphs and the correlation coefficients is a good way to gain a "feel" of the coefficients and strength of relationships.
When a pair of variables have a positive correlation will the slope in the regression equation always be positive?
Yes
The value of the correlation coefficient is always in the range 0 to 1 true or false?
FALSE: THE RANGE IS -1 to +1
What is the feasible range for r the correlation coefficient?
the correlation coefficient range is -1 to +1
Why the value of correlation coefficient is always between -1 and 1?
Why the value of correlation coefficient is always between -1 and 1?
Properties of correlation cofficient?
why correlation cofficient always lies between 1 and -1

It depends on the range of ages, but a moderate positive correlation.
What is the range of correlation coefficient and what does its value tell?
The product-moment correlation coefficient or PMCC should have a value between -1 and 1. A positive value shows a positive linear correlation, and a negative value shows a negative linear correlation. At zero, there is no linear correlation, and the correlation becomes stronger as the value moves further from 0.
In a positive correlation scatter plot as the values of the domain increase what do the values of the range do?
The values of the range also tend to increase.
What has the author W Lakin written?
W. Lakin has written: 'Short range anti-correlation of electrons in the hydrogen molecule' 'Shor t range anti-correlation of electrons in the hydrogen molecule' -- subject(s): Accessible book

Can coefficient of correlation be negative?
Yes. The range of r is from -1 to 1. See related link.
What percentage of variation in the criterion variable is accounted for by the predictor variable if the correlation between them is 50?
A correlation coefficient can only range from -1.0 to 1.0 so a 50 is not possible. Did you mean .5?
