You conduct a clinical trial to test whether a new drug relieves the symptoms of arthritis better than a placebo. you have four groups of participants, all of whom have moderately painful arthritis (rated 7 on a scale of 1 to 10). each group receives a daily pill as follows: group 1-placebo; group 2-15 mg; group 3-25 mg; group 4-50 mg. at the end of 2 weeks, participants in each group are asked to rate their pain on a scale of 1 to 10.what is the independent variable in this experiment?

the drug itself

Explanation:

The independent variable is the variable that changes irrespective of other variables.

When a change in variable is caused due to the change in the independent variable is called the dependent variable.

Here, whether a drug is effective in relieving the symptoms of arthritis is being determined. The drug will be considered effective only if the treatment group show the desired effects. The placebo control group should not show any effects of the drug. Hence, the drug is the independent variable.

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
