Describing direction and strength of correlation

Describing direction and strength of correlation.

  • Plot paired observations as separate crosses. Do not join the points.
  • A best-fit line follows the overall trend, with points balanced around it.
  • Predictions are estimates. Extrapolation is less secure, and correlation alone does not establish causation.

Example 1

Describe the direction and strength of the correlation.

Coordinate graph1234567891011510152025300
As increases, generally increases.The points lie close to a straight-line pattern.
Strong positive correlation.

Example 2

Describe the direction and strength of the correlation.

Coordinate graph12345678910115101520250
As increases, generally decreases.The points lie close to a straight-line pattern.
Strong negative correlation.
