The equation takes the form: y = A + B/x

To use the calculator, enter a list of comma-separated values for the predictor variable and response variable then click the Do Inverse Regression button.

y = A+ B/x

Correlation coefficient
r =

You can interpret the correlation coefficient r as follows:

  • 0.7<|r|≦1        strong correlation
  • 0.4<|r|<0.7     moderate correlation
  • 0.2<|r|<0.4     weak correlation
  • 0≦|r|<0.2         no correlation
