Practice Scatter Plot in Statistics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A graph that uses dots to show the relationship between two numerical variables, with each dot representing one data point.
Each dot is a person (or item) plotted by TWO measurements - like height on one axis and weight on the other. Patterns in the dots reveal relationships: do taller people weigh more? The scatter tells the story.
Example 1
mediumA scatter plot of hours studied (x) vs exam score (y) shows points rising from left to right in a roughly linear pattern. Describe the association.
Example 2
mediumGiven points: (1,2), (2,4), (3,5), (4,4), (5,8). Plot them and identify any outlier from the general trend.
Example 3
mediumA scatter plot shows the relationship between age of a car (years) and its resale value (\$). The points slope downward from left to right. Describe the association and explain what it means in context.
Example 4
mediumA scatter plot of practice hours and free-throw accuracy has points clustered tightly around an upward-sloping line. Describe the direction and strength of the association.
