## How do you work out a scatter graph?

Scatter Diagram Procedure

1. Collect pairs of data where a relationship is suspected.
2. Draw a graph with the independent variable on the horizontal axis and the dependent variable on the vertical axis.
3. Look at the pattern of points to see if a relationship is obvious.
4. 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.
