The specific independent variable in Katherine’s investigation would be the amount of sunlight each plant will recieve‚ and the specific dependent variables would be the time of day and the water. 2. Five controlled variables in this investigation would be where she would place the plants‚ the type of plant she will use‚ the type of water she uses for each plant‚ the amount of water she uses per plant and the exact times she waters the plants in a day.

on the demand pattern‚ which creates the need for inventory. The two types of demand are Independent Demand and Dependent Demand for inventories. The choice of how to control inventory depends upon the fact of whether or not the demand of the items has a dependent or an independent character. This difference is important in selecting an adequate inventory management approach. Independent Demand Independent demand exists where the rate of use for an item does not relate directly to the use of another

Information Systems Success: The Quest for Dependent Variable By William H. DeLone and Ephraim R. McLean Dependent variables are needed to be well defined in the IS success examination. Prior research more concerns on independent variables than the dependent variable. Instead‚ this article focuses on the measurement of the dependent variable. Shannon and Weaver (1949) and Mason (1978) yield six distinct categories or aspects of information systems success‚ which are system quality‚ information

variable The variable is the important aspects of the research. In research the concept are measure from variable. Variable are anythings that can take on differing or varing values. it mean that the value of variable vary from person to person‚ time to time or place to place but the meaning of variable are same to all. Thus variable are the charactestics of person‚ groups‚ objects‚ ideas‚ feeling or other thing that researcher want to measure. Variables are thus anything that can take on differing

more or less linear way. To say it differently‚ price differences between hotels underscore the presence or not of some variables expected to influence the latter. It is essential for hotels to understand how they can price their rooms and maximize yield while remaining competitive. Therefore‚ we conducted an extensive analysis to help hotel revenue managers find out what key variables influence price on Orbitz. The data were gathered from Orbitz.com directly. The data is about 1623 hotels that are located

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.” Categorical Variable 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
