Scatter Plot Math Example 1

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

Example 1

easy
Given the data pairs (x,y)(x, y): (1,2),(2,4),(3,5),(4,4),(5,6)(1,2), (2,4), (3,5), (4,4), (5,6), describe how to create a scatter plot and identify the direction of the association.

Solution

  1. 1
    Set up axes: horizontal axis for xx (explanatory variable), vertical axis for yy (response variable)
  2. 2
    Plot each ordered pair as a point: (1,2),(2,4),(3,5),(4,4),(5,6)(1,2), (2,4), (3,5), (4,4), (5,6)
  3. 3
    Observe the pattern: as xx increases, yy generally increases
  4. 4
    Identify association direction: positive association (upward trend from left to right)

Answer

The scatter plot shows a positive association between xx and yy.
Scatter plots reveal the direction (positive/negative/none), form (linear/curved), and strength of association between two quantitative variables. Always label axes and plot one point per data pair.

About Scatter Plot

A scatter plot is a graph with one quantitative variable on each axis where each data point is plotted as a dot, revealing relationships between the two variables.
