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

Symbolic Math in Matlab Matlab has a powerful symbolic math ability. Rather than making calculations on known numbers‚ we can make calculations on symbolic expressions. For example‚ what is the limit as x approaches inf of 1 + 1/2^1 + 1/2^2 + 1/2^3...+1/2^n ? Matlab can tell us. What is the integral of x^3 for any x? Matlab can tell us. Symbolic Math in Matlab Matlab allows you to create symbolic math expressions. This is useful when you don’t want to immediately compute an answer‚ or when

not all cost and revenue data is relevant. The cost data relevant for decision-making is referred to as relevant costs and that which is not useful for decision-making is non-relevant costs. On the revenue side‚ the only relevant revenue is the incremental & differential revenue. Relevant and Non-Relevant Costs: 1. Future Costs and Sunk Costs (IR): A future cost is that cost yet to be incurred and since the decision is in the future‚ future costs are relevant. A sunk cost is a historical
