The correlation between the following two lists is zero, can you explain why? 1,2,3,4,5,6,7 7,6,5,4,5,6,7 Correlation of 1st half of the list is negative and between the last half of the list is positive so they cancel out The second list is totally random with respect to the first list, therefore they don't correlate at all

1. If the linear correlation coefficient of two variables is
zero, then there is no _______________ relationship between the
variables. A linear correlation coefficient of 0.92 suggests a
________________ linear relationship than a linear correlation
coefficient of -0.86. The value of the ___________________ always
lies between -1 and 1, inclusive. If the linear correlation
coefficient of the regression line is negative, then the
____________________ of the least squares (linear) regression line
must be negative. Give a detailed interpretation of the...

Each of the following scenarios describes a correlation
between two variables. State whether the correlation is most likely
due to a coincidence, a common underlying cause, or a direct cause.
If there is an underlying cause, state what you think it is. If you
believe that one variable directly causes the other, suggest
possible physical causation.
