Unformatted text preview: iven hypotheses. Results 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 $8001$700 1 $400 $300 $200 $100 Control Operator Feedback Manager Feedback NoFeedback Figure 5-11: Results from real-time feedback experiment in the oil room. The solid bars depict the observed average weekly dollar value of electricity waste. The whiskers on the bars indicate 95% confidence intervals around the mean. following observations: We cannot conclude that operator feedback alone significantly decreased electricity waste Using the data from the control period and the first four weeks after training the operators to use the dashboard, we tested the null hypothesis that there was no difference in means using a two-sample Student's T-Test with unequal sample sizes and equal vari...
