2.4 Scatterplots and Association between Numerical Variables

Scatterplots

  • Scatterplots are used to visualise data with explanatory and response variables.
  • They consist of an x-y axis with each datapoint represented as a dot above its x-value and to the right of its y-value.
  • Scatterplots can be used to see relationships between variables. These relationships can be described in terms of form, direction and strength.
