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

Experiment 19 - Determination of the equilibrium constant for the reaction Fe3+ (aq) + SCN( (aq) = FeSCN2+ (aq) Object: To determine the equilibrium constant by a colorimetric method Theory: Colorimetric methods of analysis are usually applied to the determination of small concentrations of either inorganic or organic materials in a solution. The constituent sought must be coloured or must be capable of reacting with a reagent to produce a substance having a suitable colour. Beers Law‚ which

extraneous variables by using random assignment to experimental conditions and sometimes also by incorporating direct control and/or blocking into the design of the experiment. Each of these strategies—random assignment‚ direct control‚ and blocking—is described as follows; A researcher can directly control some extraneous variables. In the calculus test example‚ the textbook used is an extraneous variable because part of the differences in test results might be attributed to this variable. We could

hydrolysis was carried out through reflux boiling for 20 minutes with 10ml 0f 1.5M concentrations of diluted sulphuric acid. Reducing sugars concentrations were determined by spectrophotometry using the 3‚ 5 dinitrosalicylic acid (DNS) method. The first sample was operated as blank for zero. The stock solution was prepared in order to find the unknown concentration of carbohydrate cereals powder‚ jam (total sugar content) and jams (reducing sugar content).

Most manufacturers don’t have all the tools they need to reliably contain or reduce costs on products and projects. The key missing pieces typically include a view across the extended enterprise with multiple disciplines; a view of lifecycle costs‚ starting with design or project engineering and moving through supply‚ production‚ distribution‚ and‚ where relevant‚ aftermarket service; customer needs balanced with costs; forward-looking cost analysis; and a means of creating visibility and accountability
Premium Cost Costs
A process costing system is a costing system in which the cost of a product or service is obtained by assigning costs to masses of like or similar units. Unit costs are then calculated on an average basis. Process costing systems are used in industries that produce like or similar units which are often mass produced. In these industries‚ products are manufactured in a very similar way. The companies usually use the same amount of direct materials‚ direct manufacturing labor costs and manufacturing
