Dr. Sullivan is conducting a clinical trial to determine if vitamin XX can improve test performance of students in an introductory college nutrition course. Dr. Sullivan puts all the students' names in a hat and draws names to determine if they will be placed in the control or the experimental group. The experimental group receives a capsule of vitamin XX and the control group a "sugar pill" that tastes and looks identical to the vitamin XX capsule. Neither Dr. Sullivan nor the participants know who is receiving which treatment. This experiment is BEST described as

Answers

Answer 1

Answer:

double-blind, randomized, placebo controlled.

Explanation:

A double-blind experiment, often used in psychology research study, is a type of experiment in which both the participants and the researcher do not know who is receiving a particular treatment. This is to ensure that there is no bias in research results.

Hence, in this case, neitherDr. Sullivan nor the participants know who is receiving a particular treatment.

Randomized experiment is a type of experiment in which objects or individuals are randomly assigned to an experimental group. It is considered as the most reliable method of creating homogeneous treatment groups, so as to avoid biases or judgments.

Hence, in this case, Dr Sullivan randomly assigned students to both control and experimental group

Placebo-controlled experiment is the one used in testing a medical therapy, whereby there is a group that receives a sham "placebo" treatment which is specifically designed to have no real effect, aside the group of subjects that receives the treatment to be evaluated.

Hence, in this case, this is a placebo controlled experiment, as we have two distinct groups in control and experimental group.

Hence, this experiment can best be described as "double-blind, randomized, placebo controlled."

Explanation:

Imperialism can be defined as the process whereby a developed country extends and enlarges it rule over developing and under developed countries. The extension of this rule by developed countries, is often carried out through the use of the country's army or the process of colonization.

The British Imperialism over India started during the 18th Century. Great Britain ruled over India till when India gained their Independence.

During the British Imperialism of India,

certain things were achieved by Great Britain such as:

a. The development and construction of the railway system in India that allowed for trading activities in India.

b. Building of water systems, Hospitals , Schools, Telephone lines e.t.c.

There was an intended consequence or disadvantage the British had on India during imperialism. This intended consequence or disadvantage was that instead of focusing on developing the agricultural system in India to produce more food, the British government focused on the production of cash crops such as cotton.

This action by the British government lead to a great decrease in the wealth and prosperity of India as well as a great damage to the economy of India. There was an increase of famine due to food shortage and a lot of Indians died in millions due to this as a lot of Indians were starving.

What were the causes and effects of the Great Depression?

Answers

Answer:

5 Causes of The Great Depression

It was not just one factor, but  instead a combination of domestic and worldwide conditions that led to the Great Depression. As such, there is no agreed upon list of all its causes.

The effects of the Great Depression were huge across the world. Not only did it lead to the New Deal in America but  more significantly, it was a direct cause of the rise of extremism in Germany leading to World War II.

1. Stock Market Crash of 1929 - Many believe erroneously that the stock market crash that occurred on Black Tuesday, October 29, 1929 is one and the same with the Great Depression. In fact, it was one of the major causes that  led to the Great Depression. Two months after the original crash in October, stockholders had lost more than $40  billion dollars. Even though the stock market began to regain some of its losses, by the end of 1930, it just was not  enough and America truly entered what is called the Great Depression.

2. Bank Failures - Throughout the 1930s over 9,000 banks failed. Bank deposits were uninsured and thus as banks  failed people simply lost their savings. Surviving banks, unsure of the economic situation and concerned for their own  survival, stopped being as willing to create new loans. This exacerbated the situation leading to less and less  expenditures.

3. Reduction in Purchasing Across the Board - With the stock market crash and the fears of further economic woes,  individuals from all classes stopped purchasing items. This then led to a reduction in the number of items produced  and thus a reduction in the workforce. As people lost their jobs, they were unable to keep up with paying for items  they had bought through installment plans and their items were repossessed. More and more inventory began to  accumulate. The unemployment rate rose above 25% which meant, of course, even less spending to help alleviate the economic situation.

4. American Economic Policy with Europe - As businesses began failing, the government created the Smoot-Hawley  Tariff in 1930 to help protect American companies. This charged a high tax for imports thereby leading to less trade  between America and foreign countries along with some economic retaliation.

5. Drought Conditions - While not a direct cause of the Great Depression, the drought that occurred in the  Mississippi Valley in 1930 was of such proportions that many could not even pay their taxes or other debts and had to  sell their farms for no profit to themselves. The area was nicknamed "The Dust Bowl." This was the topic of John  Steinbeck's The Grapes of Wrath.
