If you are dealing with a population proportion instead of a population mean, you should use instead ourminimum required sample size calculator for proportions. Why is 30 the minimum sample size? That convention refers to a different situation: it refers to the usual minimum sample size required...
Now the minimum sample size requirement is only 3. This value applies to each sample or group, so for the 3 Sample ANOVA that would mean each sample has n = 3 for a total number of observations = 9. Note that this calculator is strictly addressing the question of alpha robustness to no...
However, since these requirements are separately addressed in EA Prerequisite Building-Level Energy Metering and EA Credit Advanced Energy Metering, projects are not required to comply with the mandatory provisions from these two sections." 2. In the first sentence under Step 3. Identify energy ...
of the calculations for multiple-zone recirculating systems, project teams must use the calculator provided by USGBC, ASHRAE's 62MZCalc spreadsheet, or energy modeling software to perform the ventilation rate procedure calculations and determine the amount of outdoor air required at the system level....
New calculator for projects performing the ASHRAE 62.1 ventilation rate procedure calculations required for EQ Prerequisite Minimum Indoor Air Quality Performance. This optional calculator can be used for LEED 2009 and LEED v4 projects and is an alternative to the ASHRAE 62.1 62MZCalc and previous 100...

The CR-POSSUM model also considers physiological and surgical variables, but reduces the number of variables required [24], while maintaining the duality of scores (physiological and operative). In the United States of America, the American College of Surgeons (ACS-NSQIP) model provides accurate es...
