Full Answer

Economics is defined as the study of how people behave with regard to the production and consumption of goods. As a social science, economics attempts to describe trends in consumer markets, such as wealth acquisition and transfer. There are two forms of economics:

  • Macroeconomics: analysis of large-scale economic activity, such as within a country or international market
  • Microeconomics: analysis of small-scale economic activity, such as between individuals and corporations

There are various themes studied within both forms of economics, including costs, production, consumption, and the rationales behind individual, corporate, national and international trade. In order to develop hypotheses around the various topic areas, economists make use of statistics and are able to compare information. Economic statistics involve quantitative data that describe either past or present trends. The data may be presented in various ways:

  • Time-related: to show trends and changes that occurred across a specific period of time, for example, unemployment rates or housing costs during a 10-year period
  • Cross-section: to show trends and changes within a specific period of time, for example, job statistics for current year college graduates

Economic statistical data sets include information about measurement, sample sizes, collection procedures and analysis processes. The data are often published for public use, such as through the United States Census or for private use, such as intra-company data used for decision-making.

    What does "r squared" mean?

    A:

    The term "R-squared," or the coefficient of determination, explains the percent of variance away from a dependent variable and is expressed as a percentage between 0 and 100. An R-squared value explains how data fits a statistical set of numbers, sometimes expressed on a graph as a line or curve surrounded by points. The closer the R-squared value is to 100, the more dependent that value is on another variable.

  • Q:

    How is the margin of error calculated?

    A:

    The margin of error is calculated using two approaches: by multiplying the critical value with the standard deviation of the statistic, or by multiplying the critical value with the standard error of the statistic when the standard deviation is unknown. In the field of statistics, the margin of error refers to the range of values contained in a confidence interval.
