A scatter graph (or scatter plot) displays the relationship between two numerical variables. Each point represents one data pair.
What Scatter Graphs Show
-
Positive correlation: Both variables increase
-
Negative correlation: One increases while the other decreases
-
No correlation: No clear pattern
When They’re Useful
-
Comparing height vs. weight
-
Studying hours studied vs. test scores
-
Analyzing temperature vs. energy usage
Trend Lines
A line of best fit helps highlight the overall direction of data and can be used to make predictions.
Scatter graphs are powerful tools for identifying patterns in science, business, and everyday life.
