Question

a tennis ball was thrown in the air. the height of the ball from the ground was recorded every millisecond from the time the ball was thrown until it reached the height from which it was thrown. the correlation between the time and height was computed to be 0. what does this correlation suggest about the relationship between the time and height?
a there is no relationship between time and height.
b there is no linear relationship between time and height.
c the distance the ball traveled upward is the same as the distance the ball traveled downward.
d the correlation suggests that there is measurement or calculation error.
e the correlation suggests that more measurements should be taken to better understand the relationship.

Explanation:

The correlation coefficient measures the strength and direction of a linear relationship. A value of 0 means there is no linear association between the two variables (time and height in this case). However, it doesn't rule out non - linear relationships.

Answer:

B. There is no linear relationship between time and height.
