    SSE/Sum of Squares for Error Calculations

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    I'm trying to calculate the sum of squares for errors (SSE) manually and I was given an example with the answer below, but I cannot figure out how they got the answer. Can you please show, or tell me how they got the answer (20) and what +...+ means between these numbers, because each time I calculate, it comes up to 18 and not 20.

    SSE = (6-8)² + (7-8)² +...+ (10-8)² + (11-13)² + (12-13)² +...+ (15-13)² = 20.

    First, why do you get 18? because you are calculating SSE = (6-8)² + (7-8)² + (10-8)² + ...
