An experiment will be conducted to determine whether children learn their multiplication facts better by practicing with flash c

ards or by practicing on a computer. Children who volunteer for the experiment will be randomly assigned to one of the two treatments. Because the children’s gender may affect the outcome, there will be blocking by gender. After practice, the children will be given a test on their multiplication facts. Why will it be impossible to conduct a double-blind experiment?

Answer: The correct answer is: it will be impossible to conduct a double-blind experiment because the kid will know whether he or she used flashcards or the computer.

Explanation:

In a double-blind experiment both researchers and patients are blinded to some important information about the study. This with the purpose of obtaining the most accurate answers, since many times people's characteristics or ideas might affect the experiment's development and the results. In the given example, it will be impossible to conduct a double-blind experiment because children (patients) are aware of the method (flashcards or the computer) used to obtain the information.

What did President Truman decide to do to stop Russia's push to spread their influence?
Karolina [17]
On June 27, 1950, President Harry S. Truman announces that he is ordering U.S. air and naval forces to South Korea to aid the democratic nation in repulsing an invasion by communist North Korea. The United States was undertaking the major military operation, he explained, to enforce a United Nations resolution calling for an end to hostilities, and to stem the spread of communism in Asia. In addition to ordering U.S. forces to Korea, Truman also deployed the U.S. 7th Fleet to Formosa (Taiwan) to guard against invasion by communist China and ordered an acceleration of military aid to French forces fighting communist guerrillas in Vietnam.
