Norm-Referenced vs. Criterion-Referenced Tests. Norm-referenced tests are specifically designed to rank test takers on a âbell curve,â or a distribution of scores that resembles, when graphed, the outline of a bellâi.e., a small percentage of students performing well, most performing average, and a small percentage performing poorly.
1 7:45 a.m. : The family leaves the house and the thermostat is set to 56Â°F. 2  By turning their thermostat back 10Â° to 15Â° for 8 hours, the family can save 5% to 15% a year on their heating bill -- a savings of as much as 1% for each degree if the setback period is eight hours long.
There have been a number of studies conducted to determine what temperature your office thermostat should be set at for optimal productivity across your workforce. And it should come as no surprise that the more studies that are done the more disagreement there is as to what that temperature is.f we look at the research that gives us 71.5 degrees F as the optimal temperature and 100% productivity we only go down in productivity as temperature increases or decreases. As temperature increases: 1  at 77 degrees F we're about 98% productive. 2  82 degrees F = 95%.
