Answer:

an ANOVA

Explanation:

ANOVA known as Analysis of Variance is used to carry out analysis in the differences among group means in a sample. ANOVA is all about the collection of statistical models and their associated estimation.

The model is based on the law of total variance. Simply, ANOVA is used to provide a statistical test of whether there are two or more population means which are equal and it then generalizes the t-test beyond means. Ronald Fisher, an evolutionary biologist and statistician developed ANOVA.

Compare and contrast the views of the federalists party and the democratic republican party
Luden [163]

The Federalist Party was in service between 1798 and 1801, and the Democratic-Republican Party was in service between 1792 and 1798.

The Federalist Party were proponents of a strong, centralized national government and a strong executive branch. Federalists did not support a Bill of Rights, supported an economy based on agriculture, believed that the Constitution was open to interpretation, and asserted that the government had the right to adopt additional powers. In foreign policy, Federalists sided with the British and opposed the French Revolution. Federalists supported Alexander Hamilton.

The Democratic-Republican Party were in support of a weak, centralized government fearing that a strong central government would lead to tyranny. The DR Party supported the Bill of Rights to supplement the Constitution in order to support the people. They believed the Constitution was a strict document that limited the federal government's ability to adopt additional powers.  The DRP often aligned itself with France and admired the French's Revolution.

rusak2 [61]

Before 1453, Europeans had enjoyed relatively easy access to the East. Trade had been going on for centuries between Europe, the Indies (roughly South and East Asia) and China through the Silk Road, a land passage. However, in 1453, with the fall of Constantinople to the Ottoman Turks, tensions between Christians and Muslims rose, and the passage became a lot more restricted and dangerous.

This change motivated Portuguese navigators to try to find another route to the East through the ocean. The first promising strategy was the Cape Route of Bartolomeu Dias in 1488, around South Africa. However, there were other proposals that suggested going west. This is what Christopher Columbus attempted, which led him to discover America. These events led to the beginning of the Age of Exploration, which ended with the exploration of the polar regions in the 20th century.
