Many researchers devise "sham" treatments for their control groups to undergo, meaning that the control group interacts with res
earchers in some way that is not thought to impact the dependent variable or the outcome. This is done to weaken the argument that the treatment group improvement may have occurred in part simply due to the attention this group received from the researchers. 1. These researchers are attempting to control for which of the following?
a. multiple treatment interference
b. the Hawthorne effect
c. selection
d. experimenter effects
Hawthorne effect: In psychology, the term "Hawthorne effect" was proposed by one of the famous researcher named Henry A. Landsberger during the 1950s, and is described as the propensity of a few individuals to perform better and work more or harder when they are being allotted as participants or subjects in a particular experiment. Therefore, the behavior of these participants is being changed because of the attention they receive from their researcher instead of any manipulation in the experiment's dependent variable.
In the question above, the given statement signifies "the Hawthorne effect".
Answer:When a large object impacts the surface of the Earth, the rock at the site of the impact is deformed and some of it is ejected into the atmosphere to eventually fall back to the surface. This results in a bowl shaped depression with a raised rim, called an Impact Crater.
Answer: The definition of parole is the release of a prisoner temporarily (for a special purpose) or permanently before the completion of a sentence, on the promise of good behavior.
