<h2>
If two sets of data are correlated, this means that: one set causes the other to happen.
</h2>
Explanation:
Correlation indicates a relationship between two or more variables, but this relationship does not suggest cause and effect. When two sets of data are correlated, it means that as one variable changes, the other variable also changes.
The correlation can be measured by calculating a statistic called as correlation coefficient. The number from -1 to +1 indicates the strength and direction of the relationship between variables. The correlation coefficient is denoted by the letter r.

Look to the explanation
Explanation:
<u><em>Average velocity:</em></u> is the average rate of change of displacement with
respect to time
Average velocity is a measure for distance traveled in a given time
We can calculate the average velocity by the rule 
where s is the displacement and t is the time
<u><em>Instantaneous velocity:</em></u> is the velocity of an object in motion at a
specific point (x , t)
instantaneous velocity is the limit of velocity as the change in time
approaches zero
We can calculate the instantaneous velocity by the rule 
<u>Average velocity</u> is <u>equal</u> to the <u>instantaneous velocity</u> when
<u>acceleration</u> is <u>zero</u>
