Patterns of Knowledge in Scatterplots

Scatterplots are used to investigate patterns which usually varies on the idea of linearity, slope, and power.

  • Linearity – knowledge sample is both linear/straight or nonlinear/curved.

  • Slope – path of change in variable Y with respect to extend in worth of variable X. If Y will increase with improve in X, slope is constructive in any other case slope is adverse.

  • Power – Diploma of spreadness of scatter within the plot. If dots are broadly dispersed, the connection is take into account weak. If dot are densed round a line then the connection is claimed to be robust.
