The Missouri Compromise was uncertain at the moment, as several of them fretted that the nation had become legally distributed along regional lines. The bill was completely repealed in the Kansas–Nebraska Act of 1854 and published undemocratic in Dred Scott v. Sandford. The Compromise of 1850 was a combination of five distinct laws established by the United States Congress in the month of September in 1850 that heated a legislative showdown among slave and free positions on the station of areas procured in the Mexican–American War.
Answer:
d) determine a cause-and-effect relationship.
Explanation:
The experiment is a type of scientific research that aims to obtain the causal relationship (cause and effect) between two variables.
Thus, the researcher manipulates and controls one or more independent variables and observes the variation in the dependent variables.
For example, suppose you suspect that the number of colors available increases the number of phones sold. At first, you analyze the normal selling rate with traditional colors. In a second moment you increase the amount of colors available and compare the new sales rate with the natural rate. If there is a difference, the sales level (dependent variable) was affected by the independent variable (available colors).
Experiments allow researchers to determine cause-and-effect relationships by controlling variables and manipulating the independent variable. Through experimental research, developmental psychologists can make causal statements about variables important for the developmental process. However, caution is needed when applying findings from the laboratory to natural environments.
Experiments allow researchers to determine a cause-and-effect relationship. In an experiment, researchers have significant control over extraneous variables and manipulate the independent variable to study its effect on the dependent variable. Through experimental research, developmental psychologists can make causal statements about variables important for the developmental process. However, researchers must be cautious about whether the findings from the laboratory translate to an individual's natural environment.
