## How do you work out a scatter graph?

Scatter Diagram Procedure

- Collect pairs of data where a relationship is suspected.
- Draw a graph with the independent variable on the horizontal axis and the dependent variable on the vertical axis.
- Look at the pattern of points to see if a relationship is obvious.
- Divide points on the graph into four quadrants.

**What are the 5 parts of a scatter plot?**

Examining X-Y (Scatter) Plots

- The Title. The title offers a short explanation of what is in your graph.
- The Legend. The legend tells what each point represents.
- The Source. The source explains where you found the information that is in your graph.
- Y-Axis.
- The Data.
- X-Axis.

### What do scatter plots tell us?

A scatterplot displays the strength, direction, and form of the relationship between two quantitative variables. A correlation coefficient measures the strength of that relationship.

**What do the dots on a scatter plot represent?**

A scatter plot is a graphical representation where the values of two data variables are plotted along the x and y axis. Each dot represents both the x and y values for a single location, such as a ZIP Code or county.

## How do you find the relationship in a scatter plot?

We often see patterns or relationships in scatterplots. When the y variable tends to increase as the x variable increases, we say there is a positive correlation between the variables. When the y variable tends to decrease as the x variable increases, we say there is a negative correlation between the variables.

**How do you describe the relationship of a scatter plot?**

When we look at scatterplot, we should be able to describe the association we see between the variables. A quick description of the association in a scatterplot should always include a description of the form, direction, and strength of the association, along with the presence of any outliers.
