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

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

Identifying Dependent and Independent Variables Instructions: For each of the following research designs‚ identify the dependent and independent variables. 1. To investigate the effects of exercise on mathematical problem-solving ability‚ a researcher assigned subjects to one of two groups. One group did 50 jumping jacks and the other group did 200. After exercising‚ both groups did a set of math problems. 2. A researcher hypothesized that talking to plants enhances their growth. To test her hypothesis

Global Variables This writing assignment will focus on global variables. A global variable is a variable every module in a program can see‚ meaning that the entire program is its scope (Gaddis‚ 2010). There are both advantages and disadvantages to using global variables and it is my intention to explore some of them here‚ starting with the disadvantages. There seems to be a lot to be said about the disadvantages of using global variables. First and foremost the scope itself can be a disadvantage

changes when placed in water. Identify the independent and dependent variables. If the rock is placed in water‚ then it’s mass will be added to the original mass. The independent variable has to do with the amount of water put onto the rock‚ the dependent variable is the mass of the rock after it has been in the water. 3. Describe‚ in detail‚ a procedure to test your hypothesis. Identify the controlled variables. The controlled variables is the mass of the rock before it has gone into the water

Of the following‚ which one is true? when an independent variable increases and the dependent variable also increases‚ the relationship between the two variables is positive. when an independent variable decreases and the dependent variable increases‚ the relationship between the two variables is inverse. On a graph the direct relationship is upward sloping and the inverse relationship is downward sloping. All of the above
