    1) The document describes an experiment measuring the temperature of a copper wire and brass disc circuit where the length of the wire was varied. 2) Regression analysis found a strong positive correlation between wire length and the square of the temperature, with the regression equation being T^2 = 38.2417L - 8.03689. 3) A second experiment was conducted using a nickel wire, and also found a very strong positive correlation between wire length and the square of the temperature, with the regression equation being T^2 = 25.46489L + 0.737786.
