bivariate analysis


Summary

Graph of y on x
Correlation != Causation

Magnitude of r, strength/how close the points are to the line of best-fit

Line of best-fit, y on x

  • Passes through the average
  • Can only predict y from known x
  • Can only predict within the range of the points

Concept

Correlation coefficient

Standard units

Exponential to linear

Extra

Always use independent(x) to predict dependent(y)
