Guidelines for interpreting correlation coefficient r :
  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

    Calculating the values for optimum earnings in a car game. Distance= money, but don't drive too fast is the only explanation given. Granted I got an extreme correlation, it seems this is very accurate.

    I work in marine engineering, and I have to limit a motors power based upon speed control alone. This regression calculator has proved extremely helpful in modelling the motors speed vs power response to come up with an approximate formula to use in a control algorithm. Whoever helped develop this interface, thank you, and great job.
