47  Difference between change in control group emissions and change in treatment group emissions
  The statistical significance (if any) of a difference, for a measurement period in the reporting period, between:
 (a) the change, between the relevant pre‑treatment period and the measurement period, in mean daily emissions of greenhouse gas at sites in the treatment group in a population in the project; and
 (b) the change, between the relevant pre‑treatment period and the measurement period, in mean daily emissions of greenhouse gas at sites in the control group in the population;
is worked out using the hypothesis test (hypothesis test 2):
where:
H0 means the hypothesis (the null hypothesis) that there is no difference between:
 (a) the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the treatment group; and
 (b) the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the treatment group under a counterfactual scenario.
Note: For the definition of counterfactual scenario, see section 5.
∆φT means the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the treatment group, in tonnes CO2‑e per day, under a counterfactual scenario.
∆ET means the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the treatment group, in tonnes CO2‑e per day, worked out using equation 10.
Halt means the hypothesis (the alternative hypothesis) that the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the treatment group under a counterfactual scenario is greater than the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the treatment group.
t means the test statistic for a single‑sample t‑test.
∆EC means the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the control group, in tonnes CO2‑e per day, worked out using equation 9.
sd means the standard deviation of the change, between the pre‑treatment period and the measurement period, in the mean daily emissions of greenhouse gas at sites in the control group, weighted by the number of days in the measurement period for which there is data, about measured energy consumption at sites in the control group, that is used for the purposes of this Part, worked out using equation 7.
fpcT means the finite population correction when using the change in mean daily emissions of greenhouse gas, between the pre‑treatment period and
