Answer: Regression-artifact
Explanation:
Regression artifact is the process in which non- random samples that represent the population is selected along with defective correlation with each other .
According to the question, cross-over effect in data can tend to eliminate the impact of regression artifact in which different treatment is received by subject in a series to cancel out regression.
Other options are incorrect because history, attrition or local history are not the factors that can be eliminated by crossover effect.Thus, the correct option is regression artifact.
Answer:
The functions of poverty
Explanation:
According to Herbert Gans, poverty has some positive functions in society.
We'll enumerate some of these functions:
- The existence of poverty ensures that society's "dirty work" will be done. Society pays low wages to people who have no other choice but to do the dirty work others wouldn't do (because it's physically dirty, dangerous, undignified)
- Poor people subsidize economic activities that benefit upper classes (for example, nannies)
- Poverty maintains the status of those who are not poor, because we live in a hierarchical society.
In this example, undocumented workers are a source of "cheap labor", without them fruits would rot in the fields, toddlers wouldn't have nannies, towels would go unlaundered and trays would go uncollected.
This is an example of one of the functions of poverty where <u>the poor people have no other choice than to do the "dirty work" that other people would not want to do</u> and also, <u>these activities benefit upper classes who do not have to worry about those things.</u>
Thus, this is an example of the functions of poverty.
Answer and explanation:
Following the deductive thinking logic, an argument can have true premises (be valid) and can have a false conclusion. It's one <u>possibility</u> of many. However, if an argument says that all of its premises are true then, consequently, the conclusion <u>must</u> be true as well.
The difference is that one is fake material that didn't come from our environment and the other did.
