3. lori created a scatterplot where the explanatory variable was the side of a square, and the response variable was the perimeter of the square. is the data positively or negatively correlated? explain.

We want to determine if side of a square and its perimeter are positively correlated

Let the side of the square be 'a' units.

Then, the perimeter of the square would be = 4×a units

Hence, we can see that for each unit increase in 'a', the perimeter would increase 4 times.

Hence, both the side and the perimeter are moving in the same direction.  Hence, they are positively correlated
