WebBecause the deviations are squared, every term is positive (except maybe a few are zero when Δxi = 0 or Δyi = 0 (i.e. for any values exactly equal to the mean). The key is the top, where nothing is squared. The top is the sum of Δxi *Δyi, so it will be positive when Δx and Δy are BOTH positive or BOTH negative.
