A researcher wants to study the effect of different levels of noise on the performance of students in a math test and a history test. The two levels of noise are low and high. The researcher uses different sets of individuals for each level and each type of test. This is an example of a(n):.

independent groups design.

Explanation:

In independent groups design, the researchers will put different subjects/participants for each different tests on the research. (this is why the students are separated to low level group and high level group.)

Typically, this type of study is being done to find for two reasons:

1. To find out a how different external occurrences can influence the condition of a certain variable.

2. To accelerate the research process. Separating the group will be faster compared to testing each test one by one.

the most likely outcome of fewer loon territories is that hawks would increase in proportion because the benefit of victory would be greater. hawks and loons are natural rivals of resources and victories in the game, since the lakes drying up affected the loons, the hawks would be benefited from the drought.

i disagree that there is little difference between adult female development and adult male development. sociological studies comparing female and male pathways to adulthood, revelead that there are sustancial differences between them. particularly, female and male differ from timing of marriage, when they began to live with children and the likelihood of combining wife/husband and parent roles.
