The results of the feedback field experiment are mixed in terms of support of the hypotheses. The
average dollars of electricity wasted per week during each phase of the field experiment are shown
in Figure 5-11. Based on our experience during the field experiment and the data, we make the

observed average weekly dollar value of electricity waste. The whiskers on the bars indicate 95%

We cannot conclude that operator feedback alone significantly decreased electricity
