Which of the confederate states were west of the mississippi river​
dimulka [17.4K]
The Trans-Mississippi Theater of the American Civil War consists of the major military operations west of the Mississippi River. The area is often thought of as excluding the states and territories bordering the Pacific Ocean, which formed the Pacific Coast Theater of the American Civil War (1861–1865).


Map of Trans-Mississippi Theater of the American Civil War, featuring only the major battles
The campaign classification established by the National Park Service of the U.S. Department of the Interior[1] is more fine-grained than the one used in this article. Some minor NPS campaigns have been omitted and some have been combined into larger categories. Only a few of the 75 major battles the NPS classifies for this theater are described. Boxed text in the right margin show the NPS campaigns associated with each section.

Activity in this theater in 1861 was dominated largely by the dispute over the status of the border state of Missouri. The Missouri State Guard, allied with the Confederacy, won important victories at the Battle of Wilson's Creek and the First Battle of Lexington. However, they were driven back at the First Battle of Springfield. A Union army under Samuel Ryan Curtis defeated the Confederate forces at the Battle of Pea Ridge in northwest Arkansas in March 1862, solidifying Union control over most of Missouri. The areas of Missouri, Kansas, and the Indian Territory (modern-day Oklahoma) were marked by extensive guerrilla activity throughout the rest of the war, the most well-known incident being the infamous Lawrence massacre in the Unionist town of Lawrence, Kansas of August 1863.

Betty Lou gives her son Pierre a piece of pecan pie if he does all his homework. betty Lou is providing Pierre with a primary reinforcer

<h3>A primary reinforcer is what?</h3>

The elements that affect human learning and behavior have long been the subject of research by behavioral psychologists. In this area of research, learning is linked to classical and operant conditioning as well as the relationship between inputs and outcomes. Stimuli are signs or events in the environment that can elicit feelings and behaviors in both people and animals. For instance, if someone has positive associations with the aroma of pizza, the aroma of freshly baked pizza may tempt them to eat that particular sort of food. In the same way that smelling spoiled or unappetizing food can make someone feel sick, it can also cause them to avoid a specific region.

These illustrations demonstrate how associations people make between components of their environment and specific outcomes can have an impact on their behavior.

Operant conditioning is a type of learning in which a specific action's results influence whether or not that action is repeated in subsequent situations. Operant conditioning can be used to teach new behaviors by employing incentives and penalties to reinforce and correct behavior. For instance, by providing rewards that would encourage or reinforce particular behaviors, some animals can be trained to follow straightforward commands.

Consequently, a natural response to a stimulus is referred to as a primary reinforcer.

The <u>ordinal data</u> is type of data is also called ranked data and expresses the comparative evaluation of various characteristics or entities, and relative assignment of each, to a class according to a set of criteria.

<u>Explanation:</u>

A categorical, quantitative category of data where there are normal, organized categories of variables and the ranges between the categories are not established is understood as an ordinal data. These information occurs on an ordinal dimension, one of the 4 calculation rates defined in 1946 by S. S. Stevens. An illustration of ordinal data is a satisfaction score on a range of 1-10. There is no uniform significance for the disparity between one score and the next in level results.
