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

Explainthe relationship between the average cost and marginal cost curve? Answer: We usually assume that the Average Cost curve is U shaped The MC curve will intercept the AC curves at its minimum point. When AC is decreasing‚ MC lies below AC - because when MC is below AC‚ producing an extra unit of output will pull down average cots When AC is increasing‚ MC lies above AC - because when MC is above AC‚ producing an extra unit of output will raise average costs Therefore MC will intercept the AC curve

The purpose of this lab was to compare the action of a catalyst (enzyme) under different environmental conditions. This was determined by performing a variety of different experiments. The first experiment was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme
