Types of Variables Binary variable Obsevations (i.e.‚ dependent variables) that occur in one of two possible states‚ often labelled zero and one. E.g.‚ “improved/not improved” and “completed task/failed to complete task.” Usually an independent or predictor variable that contains values indicating membership in one of several possible categories. E.g.‚ gender (male or female)‚ marital status (married‚ single‚ divorced‚ widowed). The categories are often assigned numerical values used as lables

Fad: The Fading Correlation Between Fashion and Social Class Change is inevitable‚ as Charles Darwin has proven through his theory of evolution. Starting from as early as the 13th century to the present day‚ fashion and its role in society has significantly evolved. The evidence of this evolution shows exactly how the connection between fashion and social status within different societies has changed over time. Fashion is a very popular part of any culture‚ with a variety of different colors‚ fabrics

The purpose of this report is to identify whether a relationship exists between macroeconomic variables and stock exchange returns in the Pakistani capital market. The techniques of multiple linear regression will be applied to understand if there is indeed a link between the two. The time series data being analyzed is on a monthly basis and spans from January 2003 to January 2009. The indicators taken as the independent variables are manufacturing production index‚ consumer price index‚ discount rate

by the healthcare organization can be classified as variable‚ fixed‚ or semi-fixed costs. Understanding the appropriate classification of these cost ’s behaviors serves management through providing specific process and product information necessary for a successful operation. The primary reason for defining an organization ’s underlying cost structure is to provide healthcare managers with a tool for forecasting costs and profits at different volume levels (Gapenski‚ 2012).

WHAT IS A RANDOM VARIABLE? A random variable assigns a number to each outcome of a random circumstance‚ or‚ equivalently‚ a random variable assigns a number to each unit in a population. It is easier to create rules for broad classes of situations and then identify how a specific example fits into a class than it is to create rules for each specific example. We can employ this strategy quite effectively for working with a wide variety of situations Involving probability and random outcomes. We
