The results showed that third graders performed better on the test than the first graders did, which was expected. However, the lower socioeconomic status children did worse on the test when they received directions in an evaluative way than the higher socioeconomic status children did when they received directions in an evaluative way.
Supermajority rules can avoid Arrow's theorem at the cost of being poorly-decisive (i.e. frequently failing to return a result). In this case, a threshold that requires a 2 / 3 {\displaystyle 2/3} majority for ordering 3 outcomes, 3 / 4 {\displaystyle 3/4} for 4, etc. does not produce voting paradoxes .
Economy of force is one of the nine Principles of War, based upon Carl von Clausewitz's approach to warfare. It is the principle of employing all available combat power in the most effective way possible, in an attempt to allocate a minimum of essential combat power to any secondary efforts.
Offensive action is the most effective and decisive way to attain a clearly defined common objective. Offensive operations are the means by which a military force seizes and holds the initiative while maintaining freedom of action and achieving decisive results. This is fundamentally true across all levels of war.
The Decisive Battle Doctrine (艦隊決戦, Kantai Kessen, "naval fleet decisive battle") was a naval strategy adopted by the Imperial Japanese Navy prior to the Second World War. The theory was derived from the writings of American naval historian Alfred Thayer Mahan .
Fundamental (or rudimentary) numeracy skills include understanding of the real number line, time, measurement, and estimation. [6] Fundamental skills include basic skills (the ability to identify and understand numbers) and computational skills (the ability to perform simple arithmetical operations and compare numerical magnitudes).
The phrases "decisive battle" and "decisive victory" have evolved over time, as the methods and scope of wars themselves changed. More modernly, as armies, wars and theaters of operation expanded — so that the gestalt (i.e., a result which is greater than the sum total – see synergy) of the overall venture was more definitive — the phrase "lost its meaning."
Illustration of the power of a statistical test, for a two sided test, through the probability distribution of the test statistic under the null and alternative hypothesis. α is shown as the blue area , the probability of rejection under null, while the red area shows power, 1 − β , the probability of correctly rejecting under the alternative.
