what kind of relationship between X ndY is indicated ,if the points of the scattered diagram tend to cluster about

1. a straight line parallel to x axis

2. a straight line parallel to y axis

3. a straight line sloping upward

4 a straight sloping downward

1. A straight line parallel to

*x*-axis implies that value of

*Y*does not change at all when the value of

*X*changes. Thus there is no linear correlation between the variables.

2. A straight line parallel to y-axis implies that value of

*X*does not change at all when the value of

*Y*changes. Thus there is no linear correlation between the variables.

3. A straight line sloping upward indicates positive correlation.

4. A straight line sloping downward indicates negative correlation.
