How to show the inverse square law from a data set

    1. The problem statement, all variables and given/known data
    Hi there! I have a data set of r (independent variable) and E (electric field strength) (dependent variable). The question asks for a non graphical method to show if there is an inverse square law relationship between the two data sets.
    --
    My attempt:
    I picked the equation of field strength in a radial field to show that E is proportional to the inverse of r squared. I then, without any obvious next move, tried to find a relationship between the two days sets. I tried simply putting the two into the formula, I tried logging E and then multiplying it by the square of r, but I have a mind black and dunno how to do it! Please help!

    Don't worry, worked it out. It was a mind blank after all!
