## How to Construct a Scatter Plot

A scatter plot gives you a visual idea of what is happening with your data. Scatter plots in statistics create the foundation for linear regression, where we take scatter plots and try to create a usable model using functions. There are just three steps to creating a scatter plot.

Sample question: create a scatter plot for the following data:

x y
3 25
4.1 25
5 30
6 29
6.1 42
6.3 46

Step 1: Draw a graph. Label the x- and y- axis. Choose a range that includes the maximums and minimums from the given data. For example, our x-values go from 3 to 6.3, so a range from 3 to 7 would be appropriate.

Step 2: Draw the first point on the graph. Our first point is (3,25).

Step 3:. Draw the remaining points on the graph.

Now these kinds of questions I could do all day. This information I can understamd without loosing my mind and trying to figure out where to start and where to end. We need more of these questions.

I can agree with Lisa, these problems I can do very easly, and its just self explanatory. and this example just makes it way better

Great example that makes it easier to understand the Scatter Plot. I love these because you can make sense of data that might otherwise be hard to see a pattern in! I absolutely love plots and graphs and visualization of data.
