Your question is missing the options. I've found the complete question online. It is as follows:
To study the effects of noise on worker productivity, researchers have on group of subjects work in a noisy room and a second group work in a quiet room. To ensure that any differences in the productivity of the two groups actually results from the different noise levels to which the groups are exposed, the researchers would use:
1) the case study
2) correlational measurement
3) naturalistic observation
4) replication
5) random assignment
Answer:
Researchers should use 5) Random assignment.
Explanation:
According to the description, the experimental design is being used to study the effects of noise on worker productivity. The most common form for experimental design happens by dividing participants into two groups, the experimental group and the control group. Change - the noisy room, in this case - is only introduced to the experimental group. Now, if researchers want to be sure that any differences in the productivity actually result from the different noise levels, they should use random assignment. That means giving every participant equal chances of being randomly assigned to each group. Random assignment is also called random allocation or randomization.
Robbery and murder where very common on the road to the west. Coming across food was rare. Many people froze or starved on the road.
But while it was terrible for most, a lot brought along pigs, chicken, wheat, and other eatable things to last them the trip. This was useful and could make for a better experience. You could tell why you and your family are traveling west, is it for a better life or do you have family over there? Where are you going? Are you rich or poor? How old are you? What is your family like, these factor in.
Answer:
true
Explanation:
Based on the information provided within the question it can be said that the statement that is being made is completely true. Deadweight loss is a cost to society that has arisen due to market innefficiency and occurs when the supply and demand of an economy are out of equilibrium. This term can be used anywhere that there is an inefficient allocation of resources.
A sit-in is a type of peaceful civil disobedience that took place during the 1960s where protesters sat themselves in businesses and public areas until they were evicted by force or their demands were met.
