Studdy Solution

STEP 1

What is this asking? What kind of relationship do we see between height and weight in this scatterplot? Watch out! Don't just look at the first few points, make sure to look at the overall trend!

STEP 2

1. Check the trend

STEP 3

Alright, let's **look** at this scatterplot!
As we move along the horizontal axis, from left to right, the height *increases*.

STEP 4

Now, what happens to the weight as the height increases?
It looks like the weight *increases* too!
As height goes up, so does weight.

STEP 5

Does this increase look roughly like a straight line?
Yes! It's not perfectly straight, but it definitely has a **linear trend**.

STEP 6

Since both height and weight are increasing together, we call this a **positive linear association**.

STEP 7

The best description of the relationship is a **positive linear association**.
