four variables proposed for this study: one dependent variable and four independent variables. The independent variable is the STSS score. The four dependent variables are gender‚ age range‚ years of experience‚ and facility location. Data for all variables were already collected. STSS score. The STSS score is the independent variable for this study. STTS scores are based on the self-reported instrument’s results ranging from 17 to 85 (Bride et al.‚ 2004). Gender. Gender is a dependent variable

01.03 Scientific Method Scenerio 2 1. 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

Temperature and Equilibrium Virtual Lab Change is influenced by many different factors in many different situations. If you imagine the 400‚000 gallons of water in a stream at the top of a hill‚ you can picture that they will flow down the hill in order to reach equilibrium. But what if the temperature outside is -40 degrees Fahrenheit? How might this change the movement of the water molecules down the hill? This virtual lab will allow you to explore how temperature changes affect two linked
