The ATE, in this case, is the difference in expected values (means) of the treatment and control groups' length of unemployment. A positive ATE, in this example, would suggest that the job policy increased the length of unemployment. A negative ATE would suggest that the job policy decreased the length of unemployment.

For example, if the fertilizer was spread by a tractor but no tractor was used on the unfertilized treatment, then the effect of the tractor needs to be controlled. A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables ). [ 1 ]
This rendered all facts about human action examinable under a normative framework defined by cardinal virtues and capital vices. "Fact" in this sense was not value-free, and the fact-value distinction was an alien concept. The decline of Aristotelianism in the 16th century set the framework in which those theories of knowledge could be revised. [6]
Negative numbers: Real numbers that are less than zero. Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero. When zero is a possibility, the following terms are often used: Non-negative numbers: Real numbers that are greater than or equal to zero. Thus a non-negative number is either zero or positive.
