relationships become increasingly more complex. Besides the examination of direct effects‚ researchers are more and more interested in moderating effects. Moderating effects are evoked by variables whose variation influences the strength or the direction of a relationship between an exogenous and an endogenous variable. Investigators using partial least squares path modeling need appropriate means to test their models for such moderating effects. We illustrate the identification and quantification of

RESEARCH METHODS VARIABLES AND HYPOTHESES Begin with stating the research question‚ the purpose of the research‚ the resources needed‚ and a plan for the research‚ including a model of the phenomenon under study. Where do research ideas come from? Curiosity; experience; need for deciding or acting; job; school; building on or contesting existing theory; available funding; etc. A preliminary research proposal‚ in one or two pages‚ a. states the research question b. states

Solutions Q7-1 Absorption and variable costing differ in how they handle fixed manufacturing overhead. Under absorption costing‚ fixed manufacturing overhead is treated as a product cost and hence is an asset until products are sold. Under variable costing‚ fixed manufacturing overhead is treated as a period cost and is expensed on the current period’s income statement. Q7-2 Selling and administrative expenses are treated as period costs under both variable costing and absorption costing. Q7-3

between two variables. Correlation will always between -1.0 and +1.0. If the correlation is positive‚ we have a positive relationship. If it is negative‚ the relationship is negative. Correlation Correlation can be easily understood as co relation. To define. correlation is the average relationship between two or more variables. When the change in one variable makes or causes a change in other variable then there is a correlation between these two variables. These correlated variables can move

independent variable. In our design with two independent variables‚ two main effects are possible: an effect of word type and an effect of rehearsal type. In other words‚ there can be as many main effects as there are independent variables. The second piece of information is whether or not there is an interaction effect. As the name implies‚ this is information regarding how the variables or factors interact. Specifically‚ an interaction effect indicates the effect of each independent variable across
