What is Variable

1.

A tangible phenomena that is directly observable and therefore measurable. Learn more in: Theoretical Constructs and Relationships in Information Systems Research

This chapter approaches this term in two senses: as mathematical variable (i.e., dependent and independent variables of functions) and as it is used in computational language, attributing a constant value for a letter. Example: v=2. Learn more in: Using OpenSCAD for Teaching Mathematics: Building an Educational Model for 3D Printing

In Question 3 the term “variables” is used in a particular sense, namely as measurable units of analysis or elements that were identified in the student written products. 59 variables were identified falling into four broad categories: general (six variables), syntactic (19 variables), lexico-grammatical (21 variables) and textual (13 variables).

It is the quantity or condition of the system that can be measured or can be manipulated to complain the task that is need. Learn more in: Temperature Modeling of a Greenhouse Environment

8.

Used in the statistical analysis, where an observation has a value for the variable that may exist in a range of values. For instance, the firm size may be a variable used in the study, with the firm size represented by the annual sales. Learn more in: The Event Study Method in Brief
