Scatter Plot Statistics Example 1

Follow the full solution, then compare it with the other examples linked below.

Example 1

medium
A 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.

Solution

  1. 1
    Step 1: Points rising from left to right indicates a positive association — as hours increase, scores tend to increase.
  2. 2
    Step 2: A roughly linear pattern suggests the relationship can be modelled with a straight line.
  3. 3
    Step 3: The association is positive and approximately linear.

Answer

Positive, approximately linear association.
Scatter plots reveal the direction (positive/negative), form (linear/non-linear), and strength (strong/weak) of the association between two quantitative variables.
