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

    Very helpful! It’s shown that for every pound of food, she exponentially breaks the line graph and just makes it into an
    Exponentially huge graph

    Purpose of use
    I was given 3 temperature measurements by a customer where X was known, and Y was given by the customer. Graphed, these measurements appeared to be linear, so this calculator allowed me to quickly compute slope/intercept values to compute the entire (useful) temperature scale from this customer''s 3 measurements.
