This program will use a statistical measure called correlation to find the critic(s) which most closely match your ratings. It will find the correlation between all the critics' ratings and your ratings and provide the best match. The box titled "corresponding correlation" refers to the numerical value of the strength of the correlation. Correlation can be anywhere from -1 to 1: 1 is a perfect match, while -1 would indicate completely opposite ratings. Look for a rating above .7; anything less would not be very useful. Note, if you get above .99, you probably didn't enter enough movies, and the result is very unreliable. The more movies you rate, the more reliable your result.
