Political Methodology
Political methodology is a subfield of political science that studies the quantitative and qualitative methods used to study politics and draw conclusions using data. Quantitative methods combine statistics, mathematics, and formal theory. Political methodology is often used for positive research, in contrast to normative research. Psephology, a skill or technique within political methodology, is the "quantitative analysis of elections and balloting". Objective political research heavily relies on political methodology as it provides rigorous methods for analysis. Quantitative methods, including statistical analysis, can allow researchers to investigate large datasets and identify patterns or trends, such as to predict election outcomes. Oppositely, qualitative methods deal with deep analysis of smaller sets of data such as interviews, documents, and case studies. This methods of analysis are more specifically useful when it comes to analyzing complicated social phenomena and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Political Science
Political science is the scientific study of politics. It is a social science dealing with systems of governance and Power (social and political), power, and the analysis of political activities, political philosophy, political thought, political behavior, and associated constitutions and laws. Specialists in the field are political scientists. History Origin Political science is a social science dealing with systems of governance and power, and the analysis of political activities, political institutions, political thought and behavior, and associated constitutions and laws. As a social science, contemporary political science started to take shape in the latter half of the 19th century and began to separate itself from political philosophy and history. Into the late 19th century, it was still uncommon for political science to be considered a distinct field from history. The term "political science" was not always distinguished from political philosophy, and the modern dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Political Campaign
A political campaign is an organized effort which seeks to influence the decision making progress within a specific group. In democracy, democracies, political campaigns often refer to election, electoral campaigns, by which representatives are chosen or referendums are decided. In modern politics, the most high-profile political campaigns are focused on general elections and candidates for head of state or head of government, often a President (government title), president or prime minister. Campaign message The message of the campaign contains the ideas that the candidate wants to share with the voters. It is to get those who agree with their ideas to support them when running for a political position. The message often consists of several talking points about policy issues. The points summarize the main ideas of the campaign and are repeated frequently in order to create a lasting impression with the voters. In many elections, the opposition party will try to get the cand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statistical Model
A statistical model is a mathematical model that embodies a set of statistical assumptions concerning the generation of Sample (statistics), sample data (and similar data from a larger Statistical population, population). A statistical model represents, often in considerably idealized form, the Data generating process, data-generating process. When referring specifically to probability, probabilities, the corresponding term is probabilistic model. All Statistical hypothesis testing, statistical hypothesis tests and all Estimator, statistical estimators are derived via statistical models. More generally, statistical models are part of the foundation of statistical inference. A statistical model is usually specified as a mathematical relationship between one or more random variables and other non-random variables. As such, a statistical model is "a formal representation of a theory" (Herman J. Adèr, Herman Adèr quoting Kenneth A. Bollen, Kenneth Bollen). Introduction Informally, a ...

Empirical Evidence
Empirical evidence is evidence obtained through sense experience or experimental procedure. It is of central importance to the sciences and plays a role in various other fields, like epistemology and law. There is no general agreement on how the terms ''evidence'' and ''empirical'' are to be defined. Often different fields work with quite different conceptions. In epistemology, evidence is what Justification (epistemology), justifies beliefs or what determines whether holding a certain belief is rational. This is only possible if the evidence is possessed by the person, which has prompted various epistemologists to conceive evidence as private mental states like experiences or other beliefs. In philosophy of science, on the other hand, evidence is understood as that which ''Scientific method#Confirmation, confirms'' or ''disconfirms'' Hypothesis#Scientific hypothesis, scientific hypotheses and arbitrates between competing theories. For this role, evidence must be public and uncont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollsters
An opinion poll, often simply referred to as a survey or a poll, is a survey (human research), human research survey of public opinion from a particular sampling (statistics), sample. Opinion polls are usually designed to represent the opinions of a population by conducting a series of questions and then extrapolating generalities in ratio or within confidence intervals. A person who conducts polls is referred to as a pollster. History The first known example of an opinion poll was a tally of voter preferences reported by the ''Raleigh Star and North Carolina State Gazette'' and the ''Wilmington American Watchman and Delaware Advertiser'' prior to the 1824 United States presidential election, 1824 presidential election, showing Andrew Jackson leading John Quincy Adams by 335 votes to 169 in the contest for the United States presidency. Since Jackson won the popular vote in that state and the national popular vote, such straw votes gradually became more popular, but they remain ...
