Answer: test-retest reliability

Explanation: In other to validate the outcome of a test or an experiment, researchers may often repeat a particular test more than once, in other to ensure that conclusion or inference drawn from the first or initial test aren't wrong. This is known as test-retest reliability. Test retest reliability involves, that the test retaken is performed under the the same condition as the first. This is to ensure that observed differences aren't due to changes in experimental conditions. In the context above, the test was conducted twice using the same participant and condition, in other to establish the validity or reliability of the first or initial test. Since the outcome of the first and second test do not conform, the intelligence test lacks test retest reliability.

test-retest reliability

How did the unstable economy in the 1920s contribute to the Great Depression?
Sophie [7]
In the 20's the U.S. was trying "to be the world's banker, food producer, and manufacturer, but to buy as little as possible from the world in return." This attempt to have a constant favorable trade balance wouldn't succeed for long. The U.S. maintained high trade barriers to protect American business, but the U.S. wouldn't buy from our European counterparts, so there's no way for them to buy from the Americans, or pay interest on U.S. loans. The weakness of the international economy certainly contributed to the Great Depression. Europe was reliant upon U.S. loans to buy U.S. goods, and the U.S. needed Europe to buy these goods to prosper. By the year 1929, 10% of American gross national product went into exports. When the foreign countries became no longer able to buy U.S. goods, U.S. exports fell 30% overnight. That $1.5 billion of foreign sales lost between 1929 to 1933 was fully one-eighth of all lost American sales in the early years of the depression.

Flura [38]
Well, one example would be a hare. In winter, they change by growing a big, fur coat to keep them warm.

Another great example would be ducks and/or chickens. When winter is approaching, they shed their old feathers (also known as "molting") and grow a new, thicker layer of feathers to keep warm. I know this from experience, because I have 2 ducks and some chickens of my own. =)
Hope this helps! ^_^
