Plotting Data

Describing Distribution

Example Continued

Step 2. Plot each point in the table as an (x, y) coordinate point.

The data is graphed below:

Distribution1-3

Step 3. Is there a relationship between the two variables?

The points are basically all doing the same thing, so there is a relationship.

Step 4. Is the graph linear or non-linear?

It is basically linear with a couple of points that do not follow the pattern.

Step 5. Is the relationship positive or negative? Is it strong or weak?

As the x-values increase, so do the y-values. Therefore, the graph is positive. Most of the points are in the same line, so it is relatively strong.
